Synthesis of 2-arylidene-6,7-dihydroimidazo[1,2-a]pyrazine-3,8(2H,5H)-diones by oxidation of 4-arylidene-2-methyl-1H-imidazol-5(4H)-ones with selenium dioxide

[Figure not available: see fulltext.] (Z)-4-Arylidene-2-methyl-1H-imidazol-5(4H)-ones containing a substituted aminoethyl group at the N-1 atom can be oxidized with an excess of selenium dioxide, resulting in the closure of additional six-membered ring with the formation of an amide group. The obtained compounds showed a substantial bathochromic shift of the absorption maxima relative to the starting (Z)-4-arylidene-2-methyl-1Himidazol-5(4H)-ones, pointing to potential applications of this method for the synthesis of new fluorescent and fluorogenic dyes.
