摘要：
Here we demonstrate the synthesis of a novel chiral Co(iii)-salen complex supported functionalized 2D-hexagonal mesoporous silica material Co(iii)(@AFS-1. This material has shown excellent catalytic activity for the regio- and enantioselective asymmetric ring opening (ARO) of terminal and meso epoxides using various aromatic as well as cyclic amines to produce chiral beta-amino alcohols having very good enantioseEectivities (ee > 99%) at ambient temperature under solvent-free neat conditions.
