An L-proline functionalized metallo-organic triangle as size-selective homogeneous catalyst for asymmetry catalyzing aldol reactions

A homochiral metal-organic triangle Co-Pro1 was achieved via self-assembly by incorporating a L-proline moiety within the corresponding ligand. Co-Pro1 comprised L-proline moieties as asymmetric catalytic active sites and a helical-like cavity, it worked as an asymmetric catalyst to prompt aldol reactions with size-, stereo-and enantioselectivity.
