Visible-Light-Induced Deboronative Oximylation of Alkyl Boronates: Access to Bioactive Oxime Ethers as Agrochemical Leads

A visible-light-induced radical transfer strategy has been developed for the efficient construction of oxime ethers using alkyl boronic esters under mild, oxidant-free conditions. The protocol exhibits a broad substrate scope and excellent functional group tolerance. Crucially, several synthesized compounds displayed potent in vitro antifungal activities against Rhizoctonia solani, matching the efficacy of commercial fungicides and highlighting their potential as promising agrochemical leads.
