Iridium-Catalyzed Selective α-Alkylation of Unactivated Amides with Primary Alcohols
摘要:
The first a-alkylation of unactivated amides with primary alcohols is described. An effective and robust iridium pincer complex has been developed for selective alpha-alkylation of tertiary and secondary acetamides involving a "borrowing hydrogen" methodology. The method is compatible with alcohols bearing various functional groups. This presents a convenient and environmentally benign protocol for alpha-alkylation of amides.

An efficient palladium-catalyzed hydrocarbonylative C–N coupling of alkenes with amides has been developed. The reaction was performed via hydrocarbonylation of alkenes, followed by acyl metathesis with amides. Both intermolecular and intramolecular reactions proceed smoothly to give either branched or linear amides in high turnover number (3500) with NH4Cl or NMP·HCl as a proton source under the palladium
