Abstract

Enantiopure dendritic polyoxometalate frameworks were prepared by assembling chiral dendritic amines and acidic POM units. The solution CD, UV/Vis and vibrational CD investigations, and the efficiency of these hybrids in the asymmetric oxidation of thioanisole to sulfoxide (14 % ee), indicate significant induced optical activity in the POM cluster. Despite the modest ee, the present reaction confirms a chirality transfer to the POM unit.
