The dinuclear magnesium complexes generated in situ from the reaction of chiral multidentate semi‐azacrown ether ligands with n‐Bu2Mg were found to be efficient catalysts for enantioselective ring‐opening of meso‐epoxides with aniline derivatives, affording the corresponding chiral β‐amino alcohols in good yields with up to 90% ee.
已发现手性多齿半氮杂半氮杂醚配体与n- Bu 2 Mg反应原位生成的双核镁配合物是介孔环氧化物与苯胺衍生物对映选择性开环的有效催化剂,提供了相应的手性β-氨基醇,产率高,ee高达90%。
