The epoxidation of 2 and 2,3-substituted naphthoquinones with t-BuOOH in aqueous buffer solutions, in the presence of bovine serum albumin (BSA) as chiral catalyst, affords the corresponding epoxynaphthoquinones with enantiomeric excess (e.e.) up to 79%. The influences on the enantioselectivity of the pH of the buffer solution, of the oxidizing agent, and of inorganic salts have also been examined.

Abstract

The epoxidation of 2 and 2,3-substituted naphthoquinones with t-BuOOH in aqueous buffer solutions, in the presence of bovine serum albumin (BSA) as chiral catalyst, affords the corresponding epoxynaphthoquinones with enantiomeric excess (e.e.) up to 79%. The influences on the enantioselectivity of the pH of the buffer solution, of the oxidizing agent, and of inorganic salts have also been examined.
