enantioenriched amines. Current methods are based on the multi-step transformation of pre-functionalized allylic electrophiles into chiral allylic amines. The enantioselective allylic amination of unactivated olefins represents a more direct and attractive strategy. We report the enantioselective synthesis of ent-sitagliptin via an allylic amination of an unactivated terminal olefin.
大多数手性药物中氮原子的存在推动了许多用于合成富含对映体的胺的策略的发展。目前的方法基于将预官能化的烯丙基亲电试剂多步转化为手性烯丙基胺。未活化烯烃的对映选择性烯丙基胺化代表了一种更直接和更具吸引力的策略。我们报告了通过未活化末端烯烃的烯丙基胺化反应对映选择性合成 ent-sitagliptin。
