摘要: 研究了5-(1-孟氧基)-3-溴-2(5H)-呋喃酮新手性源(1)与某些碳亲核试剂发生的串联不对称Michael加成/分子内亲核取代反应,反应中生成2个新的手性中心得到一般方法难以合成的光学纳二环[3.3.0]辛-3-烯类化合物.通过[α]、IR、UV、1HNMR、13CNMR、MS、元素分析以及X射线四圆衍射等方法确定了手性二环[3.3.0]辛-3-稀类化合物化学结构和绝对构型.

Abstract: The tandem asymmetric Michael addition/intramolecular nucleophilic substitution of the novel chiral source, 3-bromo-5-(1-menthyloxy)-2 (5H)-furanone (1) with some carbon nucleophiles has been investigated.The asymmetric reaction can yield optically pure 3-bicy-clo [3.3.0]octene derivatives containing two novel stereogenic chiral centers.The chemical structure and configuration of these 3-bicyclo[3.3.0]octene compounds were identified on the basis of their elemental analytical data and spectroscopic data, such as[α]D20, UV, IR,1HNMR, 13CNMR, MS and X-ray crystallography.This asymmetric reaction can provide an important strategy in synthesis of some optically pure 3-bicyclo[3.3.0]octene compounds and some biologically active molecules.

Key words: Tandem reaction, Asymmetric Michael addition/intramolecular nucleophilic sub-stitution, Crystal structure, Chiral 3-bicyclo[3.3.0]octene compound
