Transition metal-catalyzed carbonylation functionalization reaction of alkenes is an attractive research area in modern organic chemistry. However, there have been very few reports on silver-catalyzed reactions in carbonylation reactions. Herein we developed a silver-catalyzed carbamoylation and carbonylative cyclization of alkenes with oxamic acids to obtain 2-acetylamino-1-tetralone derivatives. Various desired cyclized products were formed in moderate to good yields through radical intermediates.
Keywords: carbonylation; cyclization; radical; silver catalyst; tetralone.
