ChemInform Abstract
From a range of tested title salts, differing in the counterion and the bulkiness of chiral N-substituents, isopinocampheyl derived salt IPB gives the highest enantioselectivity in epoxidation of phenylcyclohexene (Id). Some of the reaction parameters such as effects of counterion of the catalyst, of solvent system, of temperature, and of catalyst loading are studied with this compound. Several other aryl alkenes (I), (III), (V), and (VII) are epoxidized under optimized conditions to determine the effect of substrate structure.
