A catalytic enantioselective direct conjugate addition of nitroalkanes to alpha,beta-unsaturated aldehydes using diphenylprolinol silyl ether as an organocatalyst has been developed. Using this methodology as a key step, short syntheses of therapeutically useful compounds have also been accomplished.
已经开发了使用二苯基脯氨醇甲硅烷基醚作为有机催化剂将硝基烷烃催化对映选择性直接共轭加成到α,β-不饱和醛上的方法。使用该方法作为关键步骤,也已经完成了对治疗有用化合物的短合成。
