Paterno-Buchi reaction

The Paternò–Büchi reaction, named after Emanuele Paternò and George Hermann Büchi who established its basic utility and form, is a photochemical reaction that forms four-membered oxetane rings from a carbonyl and an alkene.

Much work has been done with the reaction since Dr. Thorsten Bach of the University of Marburg published a review article in 1998 on its mechanism and synthetic utility.

The Paternò–Büchi reaction has been used recently in attempt to synthesize many natural organic products. In these experiments, the chemists are chiefly concerned with the regio- and diastereoselectivity of the products.
