that bear versatile functional groups with quaternary stereogenic centers have been prepared with very high enantioselectivity from tertiary boronic esters (see scheme; Cb=N,N‐diisopropylcarbamoyl, pin=pinacolato). The preparation of allylboronic esters bearing contiguous quaternary and tertiary stereogenic centers, and applications to natural product synthesis are also reported.
固定下来:一系列具有四元立体中心的多功能官能团的底物已经由叔
硼酸酯制备,具有非常高的对映选择性(参见方案;Cb = N,N-
二异丙基氨基甲酰基,pin = pinacolato)。还报道了具有连续季和叔立体中心的
烯丙基
硼酸酯的制备,以及在
天然产物合成中的应用。
