  Synthesis and olfactory evaluation of the enantiomerically enriched forms of 7,11-epoxymegastigma-5(6)-en-9-one and 7,11-epoxymegastigma-5(6)-en-9-ols isomers, identified in Passiflora edulis

  摘要：

  A study on the synthesis of the isomers of the natural C-13 norterpenoids derivatives 7,11-epoxymegastigma-5(6)-en-9-one and 7,11-epoxymegastigma-5(6)-en-9-ols is reported. The latter compounds were prepared from readily available racemic alpha-ionone and then resolved by mean of lipase-mediated acetylation. The obtained enantiomerically forms were evaluated for their odour properties. (C) 2005 Elsevier Ltd. All rights reserved.

  constituents, being also appreciated as synthetic building blocks. This work shows the ability of unspecific peroxygenases (UPOs, EC1.11.2.1) from several fungi, some of them being described recently, to catalyze the oxyfunctionalization of α- and β-ionones and α- and β-damascones. Enzymatic reactions yielded oxygenated products such as hydroxy, oxo, carboxy, and epoxy derivatives that are interesting

  角鲨烯类化合物是最有价值的香料成分之一，也被视为合成的基础材料。这项工作显示了来自几种真菌的非特异性过氧化酶（UPOs，EC1.11.2.1）催化α-和β-紫罗兰酮和α-和β-大马康糖酮的氧化官能化的能力。酶促反应产生含氧产物，例如羟基，氧代，羧基和环氧衍生物，它们是调味品，香料和制药工业中令人感兴趣的化合物。尽管根据底物和酶观察到不同的区域选择性，但氧优先在环的烯丙基位置产生，这在与α-紫罗兰酮的反应中特别明显，形成3-羟基-α-紫罗兰酮和/或3-氧代- α-紫罗兰酮。值得注意的是与大马士革的反应，
