  Total synthesis of malyngamide X and its 7′S-epi isomer

  摘要：

  Stereoselective syntheses of malyngamide X (1) and its 7'(S)-epimer are described. A Lewis acid (Et2AlCl) mediated anti-aldol reaction was employed to generate the stereocenters C-7 and C-8. The route is convergent and provides a convenient access to the synthesis of structural variants of malyngamide X. Stereochemistry at C-7' in the molecules of natural and synthetic 1, and 7'(S)-epi 1 was confirmed by NMR chiral solvation experiments. (c) 2007 Elsevier Ltd. All rights reserved.

  Novel malyngamide structural analogs: synthesis and biological evaluation

  摘要：

  In the course of our search for new anticancer agents, a series of novel malyngamide derivatives were synthesized by sharpless asymmetric epoxidation, followed by Julia-Kocinski olefination reactions as key reaction sequence. Anticancer activities of all these derivatives were screened against IMR-32, SF-295, SKNSH, HeLa, Colon-502713, SW-620, and Hop-62 cell lines for the first time.

  The stereoselective synthesis of malyngamide M (1) was accomplished in nine steps from o-cresol in 12% overall yield. The key steps involved the Wittig reaction of an α-NHBoc aryl ketone 4 for the introduction of vinyl chloride functionality, an amidation of lyngbic acid 3 with a secondary amine 2 for the framework of target molecule, and an isomerization of a (Z)-vinyl chloride to the (E)-configuration

  麦芽酰胺M（1）的立体选择性合成是从邻甲酚开始的9个步骤，总产率为12％。关键步骤包括用于引入氯乙烯官能团的α- NHBoc芳基酮4的Wittig反应，针对目标分子框架的lyngbic acid 3与仲胺2的酰胺化以及（Z）-的异构化使用二苯甲酮作为光敏剂将氯乙烯制成（E）-构型。还合成了异麦芽酰胺M（Z - 1）。
