Chiralitytransfer: Enantiopuredendriticpolyoxometalate frameworks were prepared by assembling chiraldendritic amines and acidic POM units. The solution CD, UV/Vis and vibrational CD investigations, and the efficiency of these hybrids in the asymmetricoxidation of thioanisole to sulfoxide (14 % ee), indicate significant induced optical activity in the POMcluster. Despite the modest ee, the present
Dichlorocarbene generated from chloroform and aqueous sodium hydroxide using chiral tertiary amines as a catalyst adds enantioselectively to olefins to give chiral dichlorocyclopropane derivatives. Optical rotations of the products strongly depend on the structure of catalysts employed.
