PREFACE By their compilation of Volumes 1 and 2 of this Compendium, Ian and Shuyen Harrison filled one of the greatest needs of the synthetic community: a method for rapidly retrieving needed information from the literature by reaction type rather than by the author's name or publication date. Compendium of Organic Synthetic Methods, Volume 5, presents the functional group transformations and difunctional compound preparations of 1980, 1981, and 1982. We have attempted to follow as closely as possible the classification schemes of the first three volumes; the experienced user of the Compendium will require no additional instructions on the use of this volume. Perhaps it is fitting here to echo the Harrison's request stated in Volume 2 of the Compendium: The synthetic literature would become easily accessible and more useful if chemists could write well-organized, concise papers with charts and diagrams that allow the reader to assess quickly and easily the scope of the published research. In addition, the reporting of actual, isolated yields and detailed experimental conditions will save a great deal of wasted effort on the part of other chemists hoping to apply the reported reactions to their own synthetic problems. I wish to express my gratitude to the many people who helped to bring this book to completion: To Mrs. Rosalie Jaramillo for her patience and dedication in the preparation of the camera-ready copy; to Dr. James McKearin, Dr. Forrest Sheffy, and Ron Wilde for proofreading the manuscript with great care and offering hundreds of helpful suggestions; and to my wife Betsy for her patience, help and moral support throughout the preparation of this Compendium. Fort Collins, Colorado November 1983

INTRODUCTION Relationship between Volume 5 and Previous Volumes. Compendium of Organic Synthetic Methods, Volume 5 presents over 1000 examples of published methods for the preparation of monofunctional compounds, updating the 6000 in Volumes 1 through 4. In addition, Volume 5 contains over 1000 additional examples of preparations of difunctional compounds and various functional groups, updating the sections introduced in Volume 2. The same systems of section and chapter numbering are used in all five volumes. Classification and Organization of Reactions Forming Monofunctional Compounds. Chemical transformations are classified according to the reacting functional group of the starting material and the functional group formed. Those reactions that give products with the same functional group form a chapter. The reactions in each chapter are further classified into sections on the basis of the functional group of the starting material. Within each section, reactions are listed in a somewhat arbitrary order, although an effort has been made to put similar reactions together when possible. The classification is unaffected by allylic, vinylic, or acetylenic unsaturation appearing in both starting material and product, or by increases or decreases in the length of carbon chains; for example, the reactions t-BuOH +. t-BuCOOH, PhCH,OH + PhCOOH and PhCH=CHCH&H + PhCH=CHCOOH would all be considered as preparations of carboxylic acids from alcohols. Conjugate reduction and alkylation of unsaturated ketones, aldehydes, esters, acids, and nitriles have been placed in category 74, Alkyls from Olefins. The terms hydrides, alkyls, and aryls classify compounds containing reacting hydrogens, alkyl groups, and aryl groups, respectively; for example, RCH,-H + RCH,COOH (carboxylic acids from hydrides), RMe +. RCOOH (carboxylic acids from alkyls), RPh + RCOOH (carboxylic acids from aryls). Note the distinction between RzCO.+ R2CH2(methylenes from ketones) and RCOR’ +. RH (hydrides from ketones). Alkylations involving additions across double bonds are found in section 74, Alkyls from Olefins.

INTRODUCTION

The following examples illustrate the classification of some potentially confusing cases: RCH=CHCOOH += RCH =CH2 RCH=CHp + RCH=CHCOOH ArH + ArCOOH ArH + ArOAc RCHO+ RH RCH=CHCHO + RCH=CH2 RCHO + RCH3 R&H, + R2C0 RCH,COR + R2CHCOR RCH=CH2 + RCH2CH3 RBr+RC=CH += RC=CR ROH+RCOOH + RCOOR RCH=CHCHO -+ R2CHCH2CH0 RCH=CHCN + RCH2CH2CN

(hydrides from carboxylic acids) (carboxylic acids from hydrides) (carboxylic acids from hydrides) (esters from hydrides) (hydrides from aldehydes) (hydrides from aldehydes) (alkyls from aldehydes) (ketones from methylenes) (ketones from ketones) (alkyls from olefins) (acetylenes from halides; also (acetylenes from acetylenes) (esters from alcohols; also esters from carboxylic acids) (alkyls from olefins) (alkyls from olefins)

How to Use the Book to Locate Examples of the Preparation or Protection of Monofunctional Compounds. Examples of the preparation of one functional group from another are located via the monofunctional index on p. xi, which lists the corresponding section and page. Thus Section 1 contains examples of the preparation of acetylenes from other acetylenes; Section 2, acetylenes from carboxylic acids; and so forth. Sections that contain examples of the reactions of a functional group are found in the horizontal rows of the index. Thus Section 1 gives examples of the reactions of acetylenes that form other acetylenes; Section 16, reactions of acetylenes that form carboxylic acids; and Section 31, reactions of acetylenes that form alcohols. Examples of alkylation, dealkylation, homologation, isomerization, and transposition are found in Sections 1, 17, 33, and so on, lying close to a diagonal of the index. These sections correspond to such topics as the preparation of acetylenes from acetylenes, carboxylic acids from carboxylic acids, and alcohols and phenols from alcohols and phenols. Alkylations which involve conjugate additions across a double bond are found in section 74, Alkyls from Olefins. Examples of name reactions can be found by first considering the nature of the starting material and product. The Wittig reaction, for instance, is in Section 199 on olefins from aldehydes and Section 207 on olefins from ketones.

INTRODUCTION

xv

Examples of the protection of acetylenes, carboxylic acids, alcohols, phenols, aldehydes, amides, amines, esters, ketones, and olefins are also indexed on p. xi. The pairs of functional groups alcohol, ester, carboxylic acid, ester; amine, amide; carboxylic acid, amide can be interconverted by simple reactions. When a member of these groups is the desired product or starting material, the other member should, of course, also be consulted on the text. The original literature must be used to determine the generality of reactions. A reaction given in this book for a primary aliphatic substrate may also be applicable to tertiary or aromatic compounds. This book does not attempt to provide experimental conditions or precautions, under the assumption that the reader will study the original literature before attempting a reaction. Not to do so would be hazardous, as well as foolish. The original papers usually yield a further set of references to previous work. Subsequent publications can be found by consulting the Science Citation Index.

Classification and Organization of Reactions forming Difunctional Compounds. This chapter considers all possible difunctional compounds formed from the groups acetylene, carboxylic acid, alcohol, aldehyde, amide, amine, ester, ether, epoxide, halide, ketone, nitrile, and olefin. Reactions that form difunctional compounds are classified into sections on the basis of the two functional groups of the product. The relative positions of the groups do not affect the classification. Thus preparations of 1,2-aminoalcohols, 1,3aminoalcohols and 1,4-aminoalcohols are included in a single section. The following examples illustrate the application of this classification system: Difunctional Product

Section Title

RC=C-C=CR RCH(0H)COOH RCH=CHOMe RCHF, RCH( Br)CH,F RCH(0Ac)CH*OH RCH(0H)COOMe RCH=CHCH,COOMe RCH=CHOAc

Acetylene - Acetylene Carboxylic Acid - Alcohol Ether-Olefin Halide - Halide Halide - Halide Alcohol - Ester Alcohol - Ester Ester - Olefin Ester-Olefin

How to Use the Book to Locate Examples of the Preparation of Difunctional Compounds. The difunctional index on p. xii gives the section and page corresponding to each difunctional product. Thus Section 327 (Alcohol - Ester) contains examples of the preparation of hydroxyesters;

INTRODUCTION

Section 323 (Alcohol -Alcohol) contains examples of the preparation of diols. Some preparations of olefinic and acetylenic compounds from olefinic and acetylenic starting materials can, in principle, be classified in either the monofunctional or difunctional sections; for example, RCH=CHBr + RCH=CHCOOH, Carboxylic acids from Halides (monofunctional sections) or Carboxylic acid- Olefin (difunctional sections). In such cases both sections should be consulted. Reactions applicable to both aldehyde and ketone starting materials are in many cases illustrated by an example that uses only one of them. Many literature preparations of difunctional compounds are extensions of the methods applicable to monofunctional compounds. Thus the reaction RCI + ROH can clearly be extended to the preparation of diols by using the corresponding dichloro compound as a starting material. Such methods are not fully covered in the difunctional sections. The user should bear in mind that the pairs of functional groups alcohol, ester; carboxylic acids, ester; amine, amide; and carboxylic acid, amide can be interconverted by simple reactions. Compounds of the type RCH(OAc)CH,OAc (Ester- Ester) would thus be of interest to anyone preparing the diol RCH(OH)CH20H(Alcohol - Alcohol).
