Abstract
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.
摘要
已开发出一种使用二苯基脯氨醇硅醚作为有机催化剂，将硝基烷烃对α,β-不饱和醛进行催化对映选择性直接共轭加成的方法。以该方法作为关键步骤，还完成了具有治疗用途化合物的简短合成。
