  A general entry to 2-(2-hydroxyalkyl)piperidines via iterative asymmetric dihydroxylation to cause enantiomeric enhancement

  摘要：

  Both enantiomers of 2-(2-propenyl)piperidine (1) (76-88% ee), prepared via the first AD of 5-hexenyl azide, underwent the second AD to provide all of the four stereoisomeric 2-(2-hydroxypropyl)-piperidines (2) with enantiomeric enhancement (>98% ee). An asymmetric synthesis, starting from 2,of several 2-(2-hydroxyalkyl)piperidine alkaloids are demonstrated. (C) 1997 Elsevier Science Ltd.

  Both enantiomers of 2-(2-propenyl)piperidine 1 (76-88% ee), prepared via the first asymmetric dihydroxylation (AD) of 5-hexenyl azide, underwent the second AD to provide all four of the stereoisomeric 2-(2,3-dihydroxypropyl)piperidines 2 with enantiomeric enhancement (>98% ee). An asymmetric synthesis, starting from 2, of several 2-(2-hydroxyalkyl)piperidine alkaloids [(-)-halosaline, (+)-N-methylallosedridine, (+)-8-ethylnorlobelol, (+)-sedridine, (+)-allosedridine, (-)-allosedridine, and (+)-N-methylsedridine] and the ant defense alkaloids [(+)-tetraponerine-3 (T-3), T-4, T-7, and T-8] is demonstrated.

  The preparation of collections of structurally diverse small molecules is a useful tool for studying biology and medicine with chemistry. Herein, we demonstrate the versatility of the pure enantiomers of 2-(2-oxo-ethyl)-piperidine-1-carboxylic acid tertbutyl ester to prepare the biological active alkaloids sedridine, allosedridine, methylsedridine, methylallosedridine, ethylnorlobelol, and coniine in two steps and in a stereoselective way via a reagent-based differentiation. The described syntheses are a demonstration of the versatility of 2-(2-oxo-ethyl)-piperidine-1-carboxylic acid tert-butyl esters as chiral building blocks. (c) 2005 Elsevier Ltd. All rights reserved.
