Stereoselective syntheses of (−)-ambrox 2 and (+)-zonarol 3 were achieved based on the enzymatic syntheses of (8aS)- and (8aR)-decalin-type 1,3-diols 1, respectively. Non-racemic intermediates such as (8aS)-1 and (8aR)-1 were obtained based on the enantioselective hydrolyses of the phenolic acetal derivative (±)-7 by acylase I.
(-)-ambrox 2和(+)-zonarol 3的立体选择性合成分别基于(8a S)-和(8a R)-萘烷型1,3-二醇1的酶促合成而实现。基于酚醛缩醛衍生物(±)-7被酰基转移酶I的对映选择性水解,获得了非外消旋中间体,例如(8a S)-1和(8a R)-1。
