It was shown that the catalytic hydrogenation of α-iminophosphonates by molecular hydrogen can serve as a convenient method for the synthesis of racemic and optically active α-aminophosphonates. Up to 94% ee was achieved in the rhodium-catalyzed enantioselective hydrogenation using chiral ligand (R)-BINAP.
结果表明,分子氢对α-亚氨基膦酸酯的催化加氢反应可作为合成外消旋和旋光性α-氨基膦酸酯的简便方法。使用手性配体(R)-BINAP在铑催化的对映选择性氢化中可实现高达94%ee。
