Synthesis of Enol Ethers and Enamines by Pd‐Catalyzed Tosylhydrazide‐Promoted Cross‐Coupling Reactions

Abstract

α-Substitution is fine: α-Alkoxycarbonyl and α-aminocarbonyl compounds are good substrates for the recently developed tosylhydrazide-promoted Pd-catalyzed cross-coupling of carbonyls with aryl halides. The reaction gives rise to enol ethers and enamines, respectively, which are useful synthetic intermediates in heterocyclic synthesis. Otherwise, they can be hydrolyzed to give α,α-disubstituted aldehydes. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
