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
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
