A catalytic synthetic method of 3,4-dihydroquinazolin-4-ones has been developed. When N-(2-nitrobenzoyl)amides were treated with carbon monoxide in the presence of a catalytic amount of selenium, reductive N-heterocyclization of N-(2-nitrobenzoyl)amide efficiently proceeded to give the corresponding
