A highly efficient enantioselective Darzens reaction of aldehydes with diazoacetamides catalyzed by a (+)-pinanediol–Ti(OiPr)4 system has been developed. The cis-glycidic amides were obtained in high yields and with moderate to excellent enantioselectivity (up to 99%).
已经开发了由(+)-ane二醇-Ti(O i Pr)4系统催化的醛与重氮乙酰胺的高效对映选择性Darzens反应。所述CIS以高收率得到,并与中度至良好的对映选择性(高达99%) -缩水甘油酰胺。
