The efficiency of a cyclodehydration reaction leading to benzodiazepinones is markedly improved by N-methylation of the amide link connecting the nucleophile and the electrophile, which is attributed to its favouring both the more reactive E-rotamer and the exit of the leaving group (C) 2010 Elsevier Ltd All rights reserved
