An enantioselective synthesis of (+)-1,14-herbertenediol, and a formal enantioselective synthesis of (−)-α-herbertenol and (−)-herbertenediol, employing a lipase-promoted and a key stereoselective alkylation of a cyclopentane unit based methodology, are described. Molecular mechanics considerations that could account for the major role played by the substitution pattern of the benzene nucleus in the
(+)-1,14-herbertenediol 的对映选择性合成,以及 (-)-α-herberteneol 和 (-)-herbertenediol 的正式对映选择性合成,采用脂肪酶促进和基于环戊烷单元的关键立体选择性烷基化方法,进行了说明。描述了分子力学方面的考虑,这些考虑因素可以解释与铜烷骨架相比,herbertane 骨架中苯核的取代模式所起的主要作用。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
