saturated five- and six-membered ring ketones sometimes bearing a methyl substituent were reacted with HCN under enzyme catalysis using recombinant hydroxynitrile lyase from Hevea brasiliensis, as a rule (S)-selective, and Prunus amygdalus, (R)-selective. The resulting cyanohydrins were stereochemically characterised. The steric outcome of these transformations was interpreted by molecular modelling.
有时带有甲基取代基的杂环饱和五元和六元环酮在酶催化下使用巴西橡胶树的重组羟腈裂解酶与HCN反应(通常(S)选择性,而苦杏仁(R)选择性)。对所得的氰醇进行立体化学表征。这些转化的空间结果是通过分子建模来解释的。
