Homochiral Metal−Organic Frameworks for Heterogeneous Asymmetric Catalysis

Abstract

Homochiral crystallizations of two enantiomeric metal−organic frameworks (MOFs) Ce−<b>MDIP1</b> and Ce−<b>MDIP2</b> were achieved by using l- or d-<b>BCIP</b> as chiral inductions, respectively, where the chiralities were characterized by solid state CD spectra. Ce−<b>MDIPs</b> exhibit excellent catalytic activity and high enantioselectivity for the asymmetric cyanosilylation of aromatic aldehydes; the homochiral Cd−<b>TBT</b> MOF having l-<b>PYI</b> as a chiral adduct exhibits stereochemical catalysis toward the Aldol reactions.
