✦ Synopsis

Photoinduced One-Pot Transformation of 2-Phenyl-4-ethylidene-5(4H)-oxazolone and Allylic Alcohols to γ,δ-Unsaturated N-Benzoyl Amides.

-Photolysis of a mixture of oxazolone (I) and allylic alcohols (II) results in a novel formation of N-benzoyl amides (III). The conversion proceeds via decarbonylation of (I), nucleophilic addition of (II), photoinduced hydrogen transfer and final Claisen rearrangement. -(PARK, BONG SER;
