An efficient and practical method for optical resolution of axially chiral biaryl dials using enantiomeric tert-butanesulfinamide as resolving agent was developed. The approach offers a very convenient and straightforward access to versatile enantiomerically pure C2-symmetric biaryl dials in good yields. With the obtained axially chiral dials, stereoselective synthesis of a series of cyclic trans-1
开发了一种有效和实用的方法,用于光学拆分轴向手性联芳基拨号使用对映体叔丁烷亚磺酰胺作为拆分剂。该方法可以非常方便,直接地获得多种对映体纯的C2对称联芳基表盘,且收率很高。利用获得的轴向手性表盘,研究了光学纯形式的一系列环状反式1,2-二醇的立体选择性合成。
