The enantioselective O–H carbenoid insertion reaction with a new chiral copper(I) imidazoindolephosphine complex has been developed. The chiral copper(I) complex catalyzed the insertion of carbenoids derived from α-diazopropionates into the O–H bonds of various phenol derivatives to give the corresponding α-aryloxypropionates with up to 91% ee.
与新的手性铜(I)咪唑并吲哚膦配合物的对映选择性OH类化合物插入反应已经开发出来。手性铜(I)配合物可催化衍生自α-重氮丙酸酯的类胡萝卜素插入各种酚衍生物的O-H键中,从而得到具有91%ee的相应α-芳氧基丙酸酯。
