The synthesis of various types of optically active α-(allenylsilane-containing)glycines via a chirality-transferring ester-enolate Claisen rearrangement of α-acyloxy-α-alkynylsilanes is described. The conversion of the rearranged products into the optically active silicon-free α-(allenyl)- and α-substituted-α-(allenyl)glycines was achieved by the removal of the Me2PhSi- or TMS group from the allene
描述了通过α-酰氧基-α-炔基硅烷的手性转移酯-烯醇式克莱森重排合成各种类型的旋光性α-(含烯丙基硅烷的)甘氨酸。通过从丙二烯末端除去Me 2 PhSi-或TMS基团,将重排产物转化为旋光的无硅的α-(烯丙基)-和α-取代的-α-(烯基)甘氨酸。
