Visible-Light-Driven Competitive Stereo- and Regioisomerization of (E)-β-Nitroenones

Abstract

A combined experimental and computational investigation of the photoreactivity of (E)-β-nitroenones pointed out the occurrence of competitive pathways namely stereoisomerisation to (E)-β-nitroenones and deconjugation to β-nitro-β,γ-enones. Both processes are generated from the triplet excited state of the starting substrates.
