Two different approaches were investigated in order to prepare the title compound 2; best results were obtained when the tandem reduction/intramolecular hydroxyalkylation of the appropriate 5-alkoxy-(3-hydroxyphenyl)pentanoate was performed on an ester of chemoenzymatic origin, already bearing the two chiral centers present in 2 with the correct relative and absolute stereochemistry.
为了制备标题化合物2,研究了两种不同的方法; 当在化学酶促来源的酯进行了适当的5-烷氧基- (3-羟基苯基)戊酸甲酯的串联还原/分子内羟烷基化,已经承载两个手性中心存在于得到最佳结果2具有正确的相对和绝对立体化学。
