Enantioselective Ring-Opening Reaction of Epoxides with MeOH Catalyzed by Homochiral Metal–Organic Framework

Abstract

Abstract Two new copper metal–organic frameworks containing 2,2′-dihydroxy-1,1′-binaphthalene-5,5′-dicarboxylic acid (5,5′-H2BDA) and 2,2′-dihydroxy-1,1′-binaphthalene-4,4′-dicarboxylic acid (4,4′-H2BDA) have been prepared. X-ray structure determination of [Cu2(5,5′-BDA)2(H2O)2]·MeOH·2H2O (MOF-1) and [Cu2(4,4′-BDA)2(H2O)2]·4H2O (MOF-2) revealed similar 2D sheet structures, containing square-grid coordination networks, but differences in the stacking motif. The desolvated MOF-1 and -2 were used as Lewis acid catalysts in the asymmetric ring-opening reaction of epoxides with MeOH.
