Transition-metal-free decarbonylative alkylation towards N-aryl α-hydroxy amides via triple C–C bond cleavages and their selective deuteration

Abstract

We disclose a transition-metal-free decarbonylative alkylation reaction for the synthesis of N-aryl α-hydroxy amides via precise cleavages and reorganizations of three C–C σ bonds. For the first time, a medium-sized cycloalkyl was used as a leaving group to initiate the decarbonylative alkylation process. We also demonstrate the concept of “one-pot” inert C–C bond activation/deuteration. This strategy allows the formation of α,β-deuterated hydroxyamides by using DMSO-d₆ as a solvent.
