Retrosynthetic analysis of the structure of imidazo[1,5-a]quinoxalines made it possible to develop new convenient procedures for preparation of these compounds by reaction of 3-(alpha-chlorobenzyl)-1,2-dihydroquinoxalin-2-one with potassium thiocyanate or isocyanate as synthetic equivalent of the two-membered N- = C+ building blocks and by reaction of 3-(alpha-aminobenzyl)-1,2-dihydroquinoxalin-2-one with carbon disulfide, triethoxymethane, aromatic aldehydes, or acetic anhydride as synthetic equivalent of the one-membered RC3+ synthon.
