Radical additions onto olefins have surfaced as an increasingly powerful strategy for the synthesis of difunctionalized scaffolds. However, despite major advances, known approaches continue to be largely limited two manifolds, namely 1,2-difunctionalization alkenes and remote difunctionalization via hydrogen atom transfer (HAT). Herein, we describe a mechanistically distinct approach by photoinduced carbon-carbon (C-C) activation/ring-opening access γ,δ-unsaturated aldehydes from methylenecyclobutanols sulfonyl chlorides strain release. Remarkably, motif on products was easily removed another photocatalytic process, which enabled concise assembly natural product alatanone A. The synthetic utility our reflected versatile functional group tolerance, ample substrate scope, scalability. photocatalysis represents conceptually alternative existing 1,4-diversifications, with double bond remaining in thus obtained products.

Abstract During the past few years, electrochemical oxidative reactions through radical intermediates have emerged as an environmentally-benign, powerful platform for facile formation of C–E (E = C, N, S, Se, O and Hal) bonds single-electron-transfer (SET) processes at electrodes. Functionalized unsaturated molecules unusual structural motifs can, instance, be directly constructed under exceedingly mild reaction conditions initial attack onto alkynes. This minireview highlights recent advances in electrooxidation until June 2022, with a particular focus on additions
