The rearrangement of cinnamate diol cyclic iminocarbonates can be regioselectively controlled by using, as the nucleophile, Bu4NBr (for β[benzylic]-nitrogen regioselection) or LiI (for the α-nitrogen isomers). This discovery will expand the synthetic utilities of the cyclic iminocarbonate rearrangement and the asymmetric dihydroxylation processes.
肉桂酸酯环状亚氨基碳酸酯的重排可以通过使用Bu 4 NBr(用于β[苄基]-氮区域选择)或LiI(用于α-氮异构体)作为亲核试剂来区域选择性地控制。这一发现将扩大环状亚氨基碳酸酯重排和不对称二羟基化过程的合成效用。
