Optically active trifluoromethylcarbinols as chiral solvating agents for asymmetric transformations at a ring-nitrogen atom
Abstract
Asymmetric chlorination of the nitrogen atom of aziridines can be carried out using achiral t-butyl hypochlorite in the presence of optically active trifluoromethylcarbinols; the absolute stereochemistry of the reaction may be correlated with the chirality of the alcohol used.
