Unusual Reactivity of Aryl Aldehydes with Triethyl Phosphite and Zinc Bromide: A Facile Preparation of Epoxides, Benzisoxazoles, and α‐Hydroxy Phosphonate Esters

et al. 2015

A facile preparation of trans‐epoxides was achieved by a (EtO)3P–ZnBr2‐mediated deoxygenation reaction of the corresponding 2‐nitrobenzaldehydes. The sterically hindered analogues of 2‐nitrobenzaldehyde underwent a reaction with triethyl phosphite in the presence of ZnBr2 as the catalyst to form benzisoxazoles as the sole product. Under identical conditions, the reactions of electron‐rich as well as moderately electron‐deficient aryl aldehydes furnished the corresponding α‐hydroxy phosphonate esters.
