Abstract:
A visible-light-enabled, photocatalyst-free hydroacylation reaction of azodicarboxylic acid derivatives was described. This radical conjugate addition (RCA) protocol relied on the dual role of 4-acyl-1,4-dihydropyridine (acyl-DHP) reagents that besides being as radical reservoirs, they also enabled the conversion of radical adducts to anion intermediates via reduction. Under “catalyst-oxidant-additive free” conditions, a wide range of structurally different acyl hydrazide products were readily obtained in 56%—99% yields. The utility of this transformation was further demonstrated by the scale-up synthesis and downstream derivatization. © 2024 SIOC, CAS, Shanghai, & WILEY-VCH GmbH.
