this article, a practically interesting route for the diastereoselective synthesis of phenylpropanolamines has been demonstrated for the first time. Using racemic O-tert-butyldiphenylsilyl (TBDPS) cyanohydrins as the starting materials, various syn phenylpropanolamines and derivatives (e.g., norpseudophedrine) have been successfully prepared in exellent diastereoselectivity via a practically interesting
摘要 在本文中,首次展示了一种非对映选择性合成苯丙醇胺的实用路线。使用外消旋 O-叔丁基二苯基甲硅烷基 (TBDPS) 氰醇作为起始材料,通过一个实际有趣的过程,以优异的非对映选择性成功制备了各种顺式苯丙醇胺和衍生物(例如去甲伪麻黄碱)。图形概要
