  摘要：

  Two diastereomeric marine butenolides. (4S,10R,11R)- and (4S,10S,11S)-4,11-dihydroxy-10-methyldodec2-en-1,4-olide, possessing a syn-aldol subunit at C10 and C11 have been efficiently synthesized by using a three-module coupling strategy. The enantiomeric syn-aldol modules prepared by the syn-selective aldol reaction of the norephedrine-derived chiral propionates were coupled with the chiral C3-C7 module via 1,3-dithiane bisalkylation. The butenolide ring was then installed via a high-yielding ring-closing metathesis (RCM) reaction. Oxidation of the diastereomeric C11-alcohols furnished the corresponding C11-ketones, which are produced by the same marine microorganism. (C) 2009 Elsevier Ltd. All rights reserved.

  The syntheses and 13C NMR analyses of four diastereomeric butenolides, two of which were recently isolated from the marine microorganisms Streptomycete B 5632 and Streptoverticillium luteoverticillatum 11014 are described. The two isolated butenolides were found to be one of the two diastereomers (4S,10R∗,11R∗)-4,11-dihydroxy-10-methyl-dodec-2-en-1,4-olide (RRS-1 or SSS-1) and one of the two diastereomers

  描述了四种非对映异构的丁烯内酯的合成和13 C NMR分析，其中最近从海洋微生物Streptomycete B 5632和leptoverticillium luteoverticillatum 11014中分离了其中的两种。两个分离的丁烯羟酸内酯被认为是两个非对映体中的一个（4小号，10 - [R * ，11 - [R * ）-4,11-二羟基-10-甲基十二碳-2-烯-1,4-内酯（RRS - 1或SSS - 1）和两个非对映异构体之一（4 S，10 S ∗，11 R ∗）-4,11-二羟基-10-甲基-十二烷基-2-烯-1,4-乙交酯（SRS - 1或RSS - 1）。硫代羰基内酯的不对称1,3-偶极环加成与连接到樟脑的双极亲和体和锂化的二噻吩对映体纯的乙烯基环氧乙烷的开环是构建三个立体中心的关键步骤。包括闭环复分解和Mitsunobu反演在内的进一步研究提供了四种非对映异构丁烯内酯。
