A novel homochiral porous MOF synthesized using (R)-2,2′-dihydroxy-1,1′-binaphthyl-4,4′-dibenzoic acid was shown to be an effective heterogeneous catalyst for asymmetric Diels–Alder reaction between isoprene and N-ethyl maleimide.
Interpenetrated and non-interpenetrated homochiral metal-organic frameworks based on IJR)-2,2′-dihydroxy-1,1′-binaphthyl-5,5′-dibenzoic acid † A new example of interpenetration that is simply controlled by modifying hydroxyl function in homochiral MOFs is reported. Interpenetrated and non-interpenetrated chiral metal-organic frameworks (MOF-1 and MOF-2) were prepared by solvothermal reactions of ijCuIJNO 3 ) 2 ]Ĵ3H 2 O in N,N-dimethylformamide (DMF)-H 2 O solution with IJR)-2,2′-dihydroxy-1,1′-binaphthyl-5,5′-dibenzoic acid (H 2 L1) and IJR)-2,2′dimethoxy-1,1′-binaphthyl-5,5′-dibenzoic acid (H 2 L2), respectively. Interpenetrated chiral MOF-1 exhibited much higher catalytic performance in the Diels-Alder reaction of acrolein and 1,3-cyclohexadiene than non-interpenetrated chiral MOF-2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
