  A short enantioselective synthesis of (+)-L-733,060 via Shi epoxidation of a homoallylic carboxylate

  摘要：

  A short and efficient enantioselective synthesis of (+)-L-733,060 in 92% ee via Shi epoxidation of a homoallylic carboxylate is described. Johnson-Claisen rearrangement was employed to obtain the required carbon backbone, whilst intramolecular reductive O-to-N-ring expansion of a delta-azidolactone was used in the construction of the piperidine moiety.

  日期：——

  The γ-butenolide obtained from an organocatalyzed, direct vinylogous aldol reaction of γ-crotonolactone and benzaldehyde serves as the key starting material in the expedient synthesis of a 3-hydroxy-2-phenyl piperidine intermediate which is converted to the target 2,3-disubstituted piperidines.

  从γ-克罗通内酯和苯甲醛的有机催化直接维尼洛格斯阿尔多尔反应中获得的γ-丁内酯，作为合成目标2,3-二取代吡啶的关键起始材料，经过高效合成得到3-羟基-2-苯基呱啶中间体。
