“Bottom-up” Construction of Chiral Porous Organic Polymers for Heterogeneous Asymmetric Organocatalysis: MacMillan Catalyst Built-in Nanoporous Organic Frameworks

Abstract

Although many porous organic polymers (POPs) are embedded with chiral ligand-metal catalytic activities have been examined as heterogeneous asymmetric catalysts, examples of metal-free stereoselective POPs catalysts are very scarce. Herein, we report the bottom-up strategy approach has been used to construct MacMillan catalyst-embedded chiral porous organic polymer, Mac-CPOPs. The porosity of the Mac-CPOPs frameworks could be adjusted by varying the molecular length of the rigid structural monomers. Owing to the high Brunauer-Emmet-Teller specific surface area and the built-in character of covalently linked MacMillan catalyst, the Mac-CPOP-2 polymer can well be applied as highly efficient and recoverable heterogeneous organocatalysts in the asymmetric Diels-Alder reaction, which give products in good enantioselectivity and yields. Moreover, the Mac-CPOP-2 polymer could be reused 6 times for the symmetric Diels-Alder reaction without any significant loss of the catalytic activity and enantioselectivity.
