An efficient kinetic resolution of propargyloxy dicarbonyl compounds via asymmetric [2,3]-Wittig rearrangement was achieved by using a chiral ,-dioxide/Ni complex catalyst. Various chiral α-allenyl alcohols were obtained in high enantioselectivities under mild conditions. The utility of this method was readily demonstrated in the asymmetric synthesis of the chiral 2,5-dihydrofuran derivative.
通过使用手性二氧/镍络合物催化剂，经由不对称[2,3]-维蒂希重排实现了炔丙氧基二羰基化合物的高效动力学拆分。在温和条件下以高对映选择性获得了各种手性α-联烯醇。该方法的实用性在手性2,5-二氢呋喃衍生物的不对称合成中得到了充分证明。
