A chiral scandium–bipyridine complex catalyzes the highly enantioselective addition of phenylselenol to aromatic meso-epoxides and furnishes 1,2-seleno alcohols in good yields and up to 94% ee. In addition, a sequential, one-pot epoxide opening-reduction protocol has been developed for the direct synthesis of 1,2-diaryl carbinols.
手性scan-联吡啶配合物催化苯硒醇向芳族内消旋环氧化合物的高度对映选择性加成,并以良好的收率和高达94%的ee浓度提供1,2-硒醇。另外,已经开发出一种顺序的,一锅法的环氧开放还原方案,用于直接合成1,2-二芳基甲醇。
