Homochiral metal-organic frameworks (MOFs) were prepared through the chiral induction effect. Thus, the homochiral crystallization of Ce(NO3)˙6H2O and H4MDIP was performed with l- or d-BCIP as chiral inducers in water to give Ce-MDIP1 and Ce-MDIP2 (where no BCIP was installed), which exhibited Cotton effects exactly opposite to each other. Ce-MDIPs promoted the cyanosilylation to give the corresponding cyanohydrin derivatives quantitatively with 93 to >98% ee.
