desilylative SE2′ reaction to the ambivalent 2-bromo-1-silyl-1,3-dienes provides a novel route to the highly enantioselective construction of tertiary and quaternary propargylic stereogenic centers via axially chiral allenylsilanes.
将Pd催化的S N 2'反应和脱甲硅烷基化的S E 2'反应逐步应用到矛盾的2-溴-1-甲硅烷基-1,3-二烯上,为叔和季炔丙基的高对映选择性构建提供了一条新途径通过轴向手性烯基硅烷形成立体中心。
