A convenient palladium-catalyzed carbonylative synthesis of 4(3H)-quinazolinones from 2-bromoformanilides and organo nitros with Mo(CO)<sub>6</sub> as a multiple promoter
A novel and convenient procedure for the synthesis of quinazolinones has been developed. Using 2-bromoformanilides and organo nitros as substrates and Mo(CO)6 as a multiple promoter, the desired products were isolated in moderate to excellent yields in the presence of a palladium catalyst. Here, Mo(CO)6 was not only a CO source, but also a nitro compound reducing reagent and a cyclization promoter

We report herein a new strategy of the Ru-catalyzed intramolecular olefin hydrocarbamoylation for the regiodivergent synthesis of five- and six-membered benzo-fused lactams starting from N-(2-alkenylphenyl)formamides. Using a combined catalyst of Ru3(CO)12/Bu4NI in DMSO/toluene cosolvent (catalytic system A), a 5-exo-type cyclization proceeds favorably to form indolin-2-ones as a major product in good
