催化氢化是有机合成中较常用的方法之一。均相催化氢化是近廿年发展起来的,而利用手性催化剂进行均相催化氢化还原在不对称合成中的应用,只是近十年来才有较大的发展。手性催化剂是利用手性膦、手性碳或不对称分手与金属铑、钌等络合而制成的。用这些手性催化剂对某些烯和酮等化合 Catalytic hydrogenation is one of the more commonly used methods in organic synthesis. Homogeneous catalytic hydrogenation has developed in recent twenty years, and the use of chiral catalysts for homogeneous catalytic hydrogenation reduction in the asymmetric synthesis of the application, only in the past decade has been a greater development. Chiral catalyst is the use of chiral phosphine, chiral carbon or asymmetric break-up with the metal rhodium, ruthenium and other complexes made. With these chiral catalysts for certain alkenes and other compounds
