Organic Framework

A new 3D metal–organic framework {[Cd3(BDC)3(OPP)(DMF)2]·2DMA}n (TMU-33) has been synthesized. The performance of the imine functional group of the OPP ligand as a Brønsted base and open Cd site as a Lewis acid in this framework was investigated as cooperative catalyst.

The first enantioselective Nazarov cyclization of substrates with only one coordinating site and with proton-transfer as an enantioselective-determining step was realized by means of cooperative catalysis with a Lewis acid and a chiral Brønsted acid.
