A Simple and Highly Selective Biomimetic Oxidation of Alcohols and Epoxides with N‐Bromosuccinimide in the Presence of β‐Cyclodextrin in Water

A simple, mild and highly efficient biomimetic oxidation of various alcohols and epoxides with N-bromosuccinimide (NBS) catalyzed by β-cyclodextrin in water has been developed. A series of alcohols and epoxides were oxidized selectively at room temperature in excellent yields. This method is a direct one-pot synthesis under mild conditions using water as solvent and has many advantages over the existing methodologies.
