文摘

The reaction of dimethyl 5-(prop-2-ynyloxy)isophthalic acid, meso-alpha, and beta-di (4-pyridyl) glycol with ZnCl₂ in a methanol aqueous solution affords MOF Zn鈭扗PPG. The enantiomeric Zn鈭扚un1 and Zn鈭扚un2 were obtained through a strategy of in situ click reactions of Zn-DPPG with two opposite chiral adducts. With the l- or d-proline chiral functionality, the two Zn鈭扚uns exhibited remarkable catalytic activities in the relative asymmetric aldol reactions, leading to the formation of opposite enantiomorphs, respectively.
