Dedicated to Tuticorin Raghavachari Govindachari (1915.) T. R. Govindachari's contributions have been largely in the field of alkaloid chemistry. He was bom on July 30, 1915 in Madras (Chennai) India and obtained his B.Sc. (1934), M.Sc. (1936) and Ph.D. (1946) degreesfix)mthe University of Madras. He carried out post-doctoral work (1949) at the University of Illinois. He was mainly responsible for the structure elucidation of tylophorine and its congeners, tiliacorine, ancistrocladine, atalaphilline, and many other alkaloids. He isolated venenatine, isovenenatine and the papaya alkaloids carpaine, pseudocarpaine and assigned their structures. Diuing his stay at Illinois, he was associated with Professor Roger Adams and contributed to the structures of many pyrrolizidine alkaloids such as riddelliine, seneciophylline, arid senecionine from Senecia species. He was Professor of chemistry and Principal at Presidency College, Madras (1952-1962) and was director of the CIBA research Centre, Bombay (1963-1975). After retirement he directed work at the Amrutanjan Research Institute and the SPIC Science Foundation. Dr. Govindachari has an indefatigable interest in the study of Natural Products and has elucidated the structures of many novel oxygen heterocyclics and terpenoids like polyalthic acid and azadirachtins from the neem kernel extracts.

Preface Volume 15 of this series features four important reviews of research on alkaloids. Chapter I by B. S. Joshi, S. W. Pelletier and S. K. Srivastava is the first comprehensive review of the catbon-13 and proton NMR shift assignments and physical constants of diterpene alkaloids and their derivatives. In addition to the catalogue of spectral and physical data, the chapter includes a table of the occurrences of these alkaloids in various plant species, tables containing molecular formulas versus calculated high-resolution mass values, and calculated high-resolution mass values versus the molecular formulas of diterpenoid alkaloids, as well as seven tables summarizing the carbon-13 chemical shifts of various functional groups in diterpenoid alkaloids. Chapter 2 by J. Kim, Y.H. Choi and K.-P. Yoo is a fascinating review of the supercritical fluid extraction of alkaloids. This technique using basic modifiers, provides an alternative method for the extraction of alkaloids. Chapter 3 by S. Prabhakar and M.R. Tavares summarizes recent advances in the synthesis of Amaryllidaceae alkaloids, an important class of naturally-occurring bases and neutral compounds. The increased activity in the synthesis of these alkaloids over the last decade is undoubtedly due to the fact that certain members of this family possess interesting and useful biological properties. Many elegant syntheses, chiral and otherwise, of structures incorporating many asymmetric centres are reviewed. Chapter 4 by J.J. Li reviews radical cyclization reactions in the total synthesis of indole alkaloids. The use of free radical chemistry in the synthesis of alkaloids has grown markedly because of the mild reaction conditions, tolerance of a wide variety of functional groups, and the good stereoselectivities. Each chapter in this volume has been reviewed by at least one specialist in the field. The editor thanks these reviewers for their important contributions to this volume. Indexes for both subjects and organisms are provided. S. William Pelletier Athens, Georgia May 28,2001

Introduction

Diterpenoid alkaloids have been isolated from the genera of the families Ranunculaceae (Aconitum, Comolida, Delphinium^ Thalictrum), Garryaceae (Garraya), Rosaceae (Spiraea), and Compositae (Inula). These alkaloids can be divided into two broad categories: norditerpenoid alkaloids (based on a Ci9-skeleton) and the diterpenoid alkaloids (based on a C2o-skeleton)J The chemistry of the diterpenoid alkaloids has been reviewed in earlier literature. ^*^*^*^ Structural elucidation of norditerpenoid alkaloids is mostly straightforward since almost all the alkaloids fall in one major skeleton-type and have well defmed substitution and configurational pattern. In addition ^^C NMR data for norditerpenoid alkaloids is readily available to compare chemical shift data of alkaloids having closely related structures.^'^ Structure determination of the diterpenoid alkaloids (C20) has been a challenging task because of the diverse skeleta of these alkaloids. During the period (-1962-1972), many of the structures were determined by X-ray crystal structure determination. The development of high resolution NMR and Mass spectral instruments has facilitated the structure elucidation and determination of the stereochemistry of the diterpenoid alkaloids. The structures of more than 240 naturally occurring diterpenoid alkaloids have been determined in the past twenty five years making use of '^C NMR studies. The diterpenoid alkaloids are derived from tetra- or pentacyclic diterpenes in which C(19) and C(20) are linked with the nitrogen of |3-aminoethanol, methyl or ethylamine to form a heterocyclic ring. These alkaloids can be divided in two broad types namely, atisanes and the kauranes. The atisane skeleton contains the [2,2,2]-bicyclic ring system with the C(15)-C(16) bridge attached at C(12). This ring system incorporates an ent-aiisane skeleton, but does not obey the isoprene rule. The atisane group has been subdivided into four subtypes Al, A2, A3, and A4 as shown in Figure 1. The kaurane skeleton possesses a [3,2,l]-bicyclic ring system with C(15)- C(16) bridge connected to C(13), forming thefive-memberring D. These alkaloids are modeled on an e/7/-kaurane nucleus and obey the isoprene rule. The kaurane-type alkaloids have been divided into three subtypes Bl, B2, and B3. In contrast to the norditerpenoid alkaloids, the diterpenoid alkaloids are less oxygenated compounds. The diterpenoid alkaloids are found to be oxygenated at the C(l), C(2), C(3), C(6), C(7), C(9), C(ll), C(13), C(14), C(15), C(17), or C(19) positions. A large majority of alkaloids are oxygenated on three or four of the carbon atoms. Some unusual diterpenoid alkaloids. Acofine is the only example of the B3type having a chlorine atom at C(l) and cardionine is the sole alkaloid with a hydroxy 1 group attached at C(12). Methoxyl groups are commonly substituted on many of the carbon atoms in norditerpenoid alkaloids. Among the diterpenoid alkaloids, only two alkaloids of the B3-type, lingshanine and lingshanone, have a methoxyl group at C(l). Septatisine and septedine are the only examples of atisane-type (Al) diterpenoid alkaloids in which C(20) of the oxazolidine ring is bridged with C(14). In barbeline, barbisine, delgrandine, vakognavine and 15- deacetylvakognavine, all belonging to the A2type, the N-C(19) bond is broken and carbon-19 bears an aldehydic group.

group is oxidized to a hydoxymethyl and the N-C(20) bond is cleaved, with the formation of a ketone at C(20). In delnudine, (A2-type) the C(12)-C(16) bond is broken and a new bond is established between C(l 1) and C(16). Eight dimeric diteipenoid alkaloids, all constituting an Al-type dimerized to an A3-type have been isolated from the mother liquors of Delphinium staphisagria L. All of these alkaloids are dimerized at C(17), C(17') and form a pyran ring at the C(16), (C15') position. These alkaloids are staphidine, staphigine, staphimine, staphinine, staphirine, staphisagnine, staphisagrine and staphisine. Coryphidine and coryphine are alkaloids of the A3 and Al-type, in which the C(17) carbon is attached to hexahydro-7Vmethylindoline. In tangirine, an Al-type diterpenoid alkaloid, C(17) carbon is attached at the C(8) position to the naturally occurring norditerpenoid alkaloid 6-benzoyl heteratisine. Zeraconine and zeraconine-iV-oxide are A2 type alkaloids in which the C (17) carbon is linked to the phenolic oxygen of/7-(Ar,Af-dimethylaminoethyl) phenol to form an ether. In pukeensine, the C(17) carbon atom of one of the A4 -type diterpenoid alkaloid forms an ether linkage with the ethanolamino group of a second diterpenoid alkaloid of the A4-type. The present catalogue provides proton and/or carbon-13 NMR chemical shift assignments and physical constants for many of the naturally occurring diterpenoid alkaloids and their derivatives. The literature search is not intended to be exhaustive. It is hoped that the '^C NMR data bank will serve as a useful guide for determining the structures of newly isolated alkaloids.
