摘要

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.
