Diazo sulfonylamidines readily undergo enantioselective oxygen transfer from sulfur to carbon atom in the presence of chiral rhodium(II) carboxylates resulting in chiral sulfinylamidines. This unusual asymmetric atom transfer "reduction" occurs rapidly under mild conditions, and sulfinylamidines are obtained in excellent yield.
重氮磺酰基脒在手性铑(II)羧酸酯存在下,很容易发生硫原子到碳原子的对映选择性氧转移,生成手性亚磺酰基脒。这种不寻常的不对称原子转移“还原”在温和条件下迅速发生,并且亚磺酰基脒以优异的产率获得。
