manner by using (OC)Ru(salen)-catalyzed sulfimidation and the subsequent [2,3]sigmatropic rearrangement: treatment of allyl aryl sulfides with p-toluenesulfonyl azide in the presence of a catalytic amount of (OC)Ru(salen) followed by hydrolysis of the resulting N-allyl-N-arylthio toluenesulfonamides provided N-allyl toluenesulfonamides of high enantiomeric excess.
通过使用(OC)Ru(salen)催化的亚磺酰亚胺化和随后的[2,3]σ重排:以对甲苯磺酰基叠氮化物处理烯丙基芳基硫化物,以高度对映选择性的方式实现了不对称CN键的形成。催化量的(OC)Ru(salen),然后将所得的N-烯丙基-N-芳硫基甲苯磺酰胺水解,提供了对映体过量很高的N-烯丙基甲苯磺酰胺。
