EnantiopureC1-Symmetric Bis(imino)pyridine Cobalt Complexes for Asymmetric Alkene Hydrogenation
摘要:
Enantiopure C-1-symmetric bis(imino)pyridine cobalt chloride, methyl, hydride, and cyclometalated complexes have been synthesized and characterized. These complexes are active as catalysts for the enantioselective hydrogenation of geminal-disubstituted olefins.
通过使用手性铁络合物作为催化剂,使用N-保护的氨基酸(AAs)作为大分子配体,描述了使用水为H 2 O 2的α-取代的苯乙烯的高度对映选择性环氧化。氨基酸与铁中心协同作用,以促进H 2 O 2的有效活化,从而在较短的反应时间内以良好的收率和立体选择性(高达97%ee)催化这种具有挑战性的底物的环氧化 。
