A rhodium/sulfur–olefin complex catalyzed asymmetric 1,2-addition of arylboronic acids to six-membered 1,2,6-thiadiazinane 1,1-dioxide-type cyclic imines to access highly optically active sulfamides (95–99% ee) has been developed. By taking advantage of the simple functional group transformations, an interesting array of valuable chiral 1,3-diamines with different substitution patterns can be readily
铑/硫-烯烃复合物催化芳基硼酸与六元1,2,6-噻二嗪烷1,1-二氧化物型环状亚胺的不对称1,2-加成反应,从而获得高度旋光的磺酰胺(95-99%ee)已经被开发出来。通过利用简单的官能团转化,可以容易地以高度对映体富集的方式获得有趣的有价值的具有不同取代模式的手性1,3-二胺阵列。
