Protective groups in organic synthesis

From the reviews of the previous editions: * "For completeness, the authors . . . include protective groups and techniques for formation and cleavage that are seldom used as well as those that are more common. . . . Anyone who does organic synthesis must have convenient access to this book." -Journal of the American Chemical Society. * "Essential to the modern synthetic organic chemist . . . should be in the libraries of all academic, governmental, and industrial organizations concerned with organic synthesis." -Polymer News. Reflecting the latest advances in protective group methodology, this Third Edition of the proven laboratory reference is expanded by more than 50%, providing readers with a comprehensive compendium of 1,050 of the most useful protective groups as well as 5,350 references to original publications. Protective groups are organized by six major organic functional groups: hydroxyl, amino, carboxyl, carbonyl, sulfhydryl, and phosphate groups (the last new to this edition). Also added in this edition are protection of the alkyne-CH, expanded coverage of protection of all groups, and many new enzymatic methods of protection and deprotection. Each chapter briefly describes the classes of available protective groups, followed by an in-depth look at the chemistry of individual protective groups, their properties, and the best methods of formation and cleavage. Ten reactivity charts with more than 28,000 entries summarize the relative reactivities of 270 commonly used protective groups with 108 reagents. This book will be an indispensable reference for synthetic chemists and students.

Part One. Synthesis of Optically Active Tryptophan Derivatives with Potential Activity as Indoleamine 2,3-dioxygenase Inhibitors: An Approach Via Asymmetric Catalytic Hydrogenation. Part Two. Design, Synthesis and Pharmacology of Selective Ligands for Alpha1-containing GABA(A)/benzodiazepine Receptor Subtypes: SAR Studies of Beta-carbolines at Positions -3 and -6 and Their Corresponding Bivalent Ligands. Part Three. First Enantiospecific Total Synthesis of the Important Biogenetic Intermediates, (+)-polyneuridine and (+)-polyneuridine Aldehyde, as Well as 16-epi-vellosimine and Macusine A.

Part III. The first stereospecific total synthesis of (+)-polyneuridine aldehyde 17, 16-epivellosimine 19, (+)-polyneuridine 22 and macusine A 23 has been accomplished from commercially available D-(+)-tryptophan methyl ester. D-(+)-Tryptophan has served here both as the chiral auxiliary and the starting material for the synthesis of the common intermediate, (+)-vellosimine 27. This alkaloid was available in enantiospecific fashion in seven reaction vessels in 27% overall yield from D-(+)-tryptophan methyl ester 28 via a combination of the asymmetric Pictet-Spengler reaction, Dieckmann cyclization, and a stereocontrolled intramolecular enolate-driven palladium-mediated cross-coupling reaction. An enantiospecific total synthesis of (+)-polyneuridine aldehyde 17, which was proposed as an important biogenetic intermediate in the biosynthesis of quebrachidine 6, was then accomplished in an overall yield of 14.1% in 13 reaction vessels from D-(+)-tryptophan ethyl ester 28. Aldehyde 27 was protected as the Na-Boc aldehyde 63, and then converted into the prochiral C (16)-quaternary diol 64 via the practical Tollens' reaction and deprotection. The DDQ-mediated oxidative cyclization and TFA/Et3SiH reductive cleavage served as protection/deprotection step to provide a versatile entry into the three alkaloids, polyneuridine aldehyde 17, polyneuridine 22 and macusine A 23 from quarternary diol 26. The chemospecific and regiospecific oxidations of the 16-hydroxymethyl group contained in the axial position in contrast to the equatorial hydroxymethyl group was achieved with the Corey-Kim reagent to provide the desired aldehydes, polyneuridine aldehyde 17 and 16-epi-vellosimine 19 with absolute diastereoselectivity.

Objectives and synthetic approach The unique and complex architecture of the
above-mentioned indole alkaloids, coupled with their largely unexplored
potential in medicine or as tools for biological studies, make these compounds
attractive ...
