New cage-fused polyaza polycyclic systems based on thioglycolurils and alkanediamines

New aspects of multicomponent condensation reactions of ethylene/propylenediamine, formaldehyde and unsubstituted and 1-methyl substituted semithio- and dithioglycolurils have been examined. Ethylene-linked 2,3a,4a,6,9,10a,11aheptaaza-6,9-methanobenzo[cd]cyclonona[gh]pentalene and 2,6:10,14-dimethano-2,6,7a,8a,10,14,15a,16a-octaazadicyclodeca[cd,gh]pentalene as well as their simpler analogues were synthesized, and their structures were proved by 1D and 2D NMR spectroscopy, HRMS and X-ray analysis.
