A novel Ti(Oi‐Pr)4 mediated olifination between Julia reagent and aldehydes has been developed. By this method, a series of substituted vinylsulfones are prepared under mild conditions, all products are exclusively E isomers. All the structures of these compounds were confirmed by 1H NMR, 13C NMR HRMS and IR.
已开发出一种新的由Ti(O i- Pr)4介导的Julia试剂和醛之间的加脂反应。通过这种方法,可以在温和的条件下制备一系列取代的乙烯基砜,所有产物均为E异构体。这些化合物的所有结构均通过1 H NMR,13 C NMR HRMS和IR确证。
