An efficient asymmetric ring-opening (ARO) reaction of -epoxides with aromatic amines catalysed by a series of homochiral metal-organic frameworks (MOFs) was carried out. Excellent results (up to 95% ee) for the ARO of cyclohexene oxide with several aromatic amines were achieved with a homochiral MOF derived from the ligand ()-2,2'-dihydroxyl-1,1'-binaphthalene-5,5'-dicarboxylic acid. Furthermore, homochiral MOFs based on ()-2,2'-dihydroxy-1,1'-binaphthyl-4,4'-di(4-benzoic acid) and ()-2,2'-diethoxy-1,1'-binaphthyl-4,4'-di(5-isophthalic acid) catalysed ARO reactions of -stilbene oxide with 1-naphthylamine in high yield (up to 95%) and excellent enantioselectivity (up to 97%) of the β-amino alcohol. The MOF catalysts were recoverable and recyclable with retention of their performance.
进行了一系列手性金属有机骨架(MOF)催化的环氧化合物与芳香胺的高效不对称开环(ARO)反应。使用源自配体()-2,2'-二羟基-1,1'-联萘-5,5'-二羧酸的手性MOF,实现了环氧环己烷与几种芳香胺的ARO反应的优异结果(对映体过量高达95%)。此外,基于()-2,2'-二羟基-1,1'-联萘基-4,4'-二(4-苯甲酸)和()-2,2'-二乙氧基-1,1'-联萘基-4,4'-二(5-间苯二甲酸)的手性MOF催化了氧化芪与1-萘胺的ARO反应,β-氨基醇的产率高(高达95%)且对映选择性优异(高达97%)。MOF催化剂可回收且可循环使用,并保持其性能。
