The incorporation of oxygen atoms from air under aerobic conditions plays an important role in organic synthesis. Herein, Brønsted acids are found to be a two-in-one strategic catalyst transform enamines β-oxoamides and amines pyrrolin-4-ones without external photocatalyst visible-light conditions. acid can inhibit the C-C bond fragmentation [2 + 2] adduct enamine

Alcohols are the most commercially abundant, synthetically versatile and operationally convenient functional groups in organic chemistry. Therefore, a strategy that utilizes hydroxy-containing compounds to develop novel bond disconnection formation process would achieve molecular diversity. Herein, deconstructive for generation of quinoxalin-2(1H)-one derivatives has been developed from alcohol precursors via oxy-radical-induced β-fragmentation. Additionally, 1,5-HAT deoxygenation by P(III) along with oxy-radical were demonstrated as alternative pathways this transformation. Furthermore, deep-seated reorganization few terpenes carbon framework, unique activity inhibition against growth pathogenic fungi was observed.
