Significance
A metal-organic framework (MOF) based Fe³+ catalyst was developed and applied to the Mukaiyama aldol reaction. Thus, the MOF-based Fe³+, UMCM-1-AMFesal, was prepared by condensation of MOF composite UMCM-1-NH2 with acid anhydride 1 followed by metalation with Fe(acac)3. The Mukaiyama aldol reaction of aldehydes 5a,b and a silyl ketene acetal 6 was carried out with UMCM-1-AMFesal (0.1 mol% Fe) to give the corresponding β-hydroxy esters in 7011% yield (7a) and 5318% yield (7b). The catalyst was reused twice without loss of catalytic activity.
