  Short enantioselective synthesis of sedridines, ethylnorlobelols and coniine via reagent-based differentiation

  摘要：

  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.

  for the synthesis of 2-substituted pyrrolidine and piperidine alkaloids containing 1,3-aminoketone and 1,3-amino alcohol units. The utility of the protocol is demonstrated by asymmetric synthesis of 12 natural products of which asymmetric synthesis of (−)-N-methylpelletierine is presented for the first time. The one-carbon homologation described also provides an alternate route for the synthesis of key

  本文描述了由亨利和Nef组合反应开发的协同方案，用于合成含有1,3-氨基酮和1,3-氨基醇单元的2-取代的吡咯烷和哌啶生物碱。该协议的实用性通过12种天然产物的不对称合成得到了证明，其中首次出现了（-）- N-甲基胆碱的不对称合成。所描述的一碳同系物还提供了另一种合成关键中间体高脯氨醇和高胡椒醇的中间体的途径，这些中间体用作几种生物碱的合成前体，并由α-氨基酸构建β-氨基酸。

  Avenues to asymmetric alkaloids! Various 2‐substituted pyrrolidine and piperidine chiral bioactive natural products were synthesized using a ‘chiral pool’ method. l‐proline and l‐pipecolinic acids with one chiral center served as the best precursors for the synthesis of these alkaloids. Overall, 14 total synthetic and 11 formal synthetic approaches were developed.
