Abstract(summary):

A novel glycoluril scaffold 1, namely 1,6-(1,2-xylylene)-3,4-(1,3-dimetheneyl-hexahydropyrimidine)tetrahydroimidazo[4,5-d]imidazole-2,5(1H,3H)-dione, was synthesized by the Mannich reaction of 1,6-(1,2-xylylene)tetrahydroimidazo[4,5-d]imidazole-2,5(1H,3H)-dione 5 with propanediamine and paraformaldehyde. The yielded product 1 was confirmed with IR, NMR, EI-MS. X-ray crystallographic technique was also conducted and the result showed the crystal belongs to monoclinic system, space group P2(1)/c with unit cell parameters a = 10.6892(11) angstrom, b = 12.1226(9) angstrom, c = 13.7822(13) angstrom, alpha = 90 degrees, beta = 112.620(4)degrees,gamma = 90 degrees, V = 1648.5(3) angstrom(3), Z = 4, D-c = 1.428, M-r = 354.41, mu = 0.098 mm(-1), F(000) = 752, R-1 = 0.0522 and wR(2) = 0.1138. A novel molecular scaffold, containing a heterocyclic ring instead of an aromatic ring, was synthesized by the Mannich reaction based on glycoluril.
