A Cr(salen)-based metal-organic framework as a versatile catalyst for efficient asymmetric transformations.

A porous Cr(salen)-MOF can serve as an efficient and effective heterogeneous catalyst for a series of important asymmetric transformations including the Nazarov cyclization, aminolysis reaction, and Diels-Alder and hetero Diels-Alder reactions, resulting in comparable or superior diastereo- or enantioselectivity with respect to the corresponding homogeneous systems.
