An efficient one‐pot synthesis of hydroxamicacids from aldehydes and hydroxylamine is described. A fast, visible‐light‐mediated metal‐free hydroacylation of dialkyl azodicarboxylates was used to develop the subsequent addition of hydroxylamine hydrochloride. A range of aliphatic and aromatic aldehydes were employed in this reaction to give hydroxamicacids in high to excellent yields. Application

Elaboration of the Effective Multi-Target Therapeutic Platform for the Treatment of Alzheimer’s Disease Based on Novel Monoterpene-Derived Hydroxamic Acids
Novel monoterpene-based hydroxamicacids of two structural types were synthesized for the first time. The first type consisted of compounds with a hydroxamate group directly bound to acyclic, monocyclic and bicyclic monoterpene scaffolds. The second type included hydroxamicacids connected with the monoterpene moiety through aliphatic (hexa/heptamethylene) or aromatic linkers. An in vitro analysis

Dioxazolones and phosphines have been used to access N-acyl iminophosphoranes in copper(I) catalysis under simple thermal conditions. The synthetic utility of this protocol is demonstrated by a broad range of substrates with an excellent atom-economy. The optimization process showed that copper demonstrated as catalytic amount toward the targeted transformation. Functionalization studies of N-acyl
