The asymmetric direct vinylogous aldol reaction of unactivated γ-butenolide with aldehydes has been developed, giving the corresponding 5-(1′-hydroxy)butenolide derivatives in high yields (up to 93%) and enantioselectivities (up to 83% ee) under mild conditions.
已开发出未活化的γ-丁烯内酯与醛类的不对称直接乙烯基醛醇缩合反应,可在温和的条件下以高收率(高达93%)和对映选择性(高达83%ee)提供相应的5-(1'-羟基)丁烯醇内酯衍生物。情况。
