  New synthesis of all the four stereoisomers of indolizidine 209D and their affinity for nicotinic acetylcholine receptor

  摘要：

  Both enantiomers of a 2-(4-pentenyl)pyrrolidine derivative 4 (65-90% ee), prepared via the asymmetric dihydroxylation (AD) of terminal olefin 2, underwent a second AD to provide all of the four stereoisomers of indolizidine 209D 1 with enantiomeric enhancement (92-98% ee). The affinity of 1 for nicotinic acetylcholine receptor was evaluated. (C) 1998 Elsevier Science Ltd. All rights reserved.

  We report herein an efficient and general method for the decarboxylative azidation of aliphatic carboxylic acids. Thus, with AgNO3 as the catalyst and K2S2O8 as the oxidant, the reactions of various aliphatic carboxylic acids with tosyl azide or pyridine-3-sulfonyl azide in aqueous CH3CN solution afforded the corresponding alkyl azides under mild conditions. A broad substrate scope and wide functional

  and seven-membered epoxyazides 3b,c underwent smooth cyclization to give 5-hydroxymethyl azepine 4b and 5-hydroxymethyl azocine 4c, respectively, as a single detectable diastereomer. This novel methodology was elegantly applied in the stereoselective total synthesis of indolizidine alkaloids 167B and 209D. Further, the enantioselective total synthesis of natural and unnatural indolizidine alkaloids 167B
