Optical resolution of α- (2,3) and β-haloacetylenic alcohols (13,14) which have two chiral carbons at the 1,2- and 1,3-positions, respectively, was performed efficiently by complexation with brucine. By the same method, α,β-dichloroacetylenic alcohols (8,9) which have three chiral carbons at the 1,2,3-positions were also resolved.
利用
布鲁辛(brucine)进行络合,高效地实现了分别在1,2-和1,3-位置具有两个手性碳的α-(2,3)和β-卤代
乙炔醇(13,14)的光学拆分。通过相同的方法,同样在1,2,3-位置具有三个手性碳的α,β-二
氯代
乙炔醇(8,9)也得到了拆分。
