Preparation of tertiary amides via aryl, heteroaryl, and benzyl organozinc reagents; scope and limitations
摘要:
A facile synthetic protocol for the preparation of tertiary amides has been developed. The title compounds have been successfully obtained by the Pd-catalyzed cross-coupling reactions of readily available aryl and benzyl organozinc reagents with the appropriate carbamoyl chlorides.

nucleophiles to access carbonyl and alkene motifs. Except for the hydrolysis (yielding carboxylic acids),27 to the best of our knowledge, acylation operations with heteroatom-based nucleophilic elements remain unexplored. Of note, the inverse process (i. e. conversion of esters to Weinreb amides) is one of the best methods for preparing N-methyl-N-methoxyamides.23 Herein, we document the chemoselective transformation
