Intramolecular reductive cross-coupling of unsymmetrical dibenzylidene sulfamides generates the corresponding cyclic sulfamides in good yield. These intermediates are readily converted to the free, unsymmetrical 1,2-diaryl ethanediamines.
不对称的二亚苄基磺酰胺的分子内还原性交叉偶联以良好的产率产生相应的环状磺酰胺。这些中间体很容易转化为游离的,不对称的1,2-二芳基乙二胺。
