A simple and efficient copper-catalyzed method has been developed for synthesis of bicyclic pyrimidinones containing six-, seven-, eight-membered rings undermildconditions. The protocol uses readily available 2-bromocycloalk-1-enecarboxylic ac- , ids, amidines, and guanidines as the starting materials, copper-catalyzed cascade couplings provide the corresponding bicyclic pyrimidinones without addition

overcome some of the disadvantages of classical inhibitors, there has been considerable interest in the synthesis and evaluation of nonclassical thymidylatesynthaseinhibitors, which could enter cells via passive diffusion. In an attempt to elucidate the role of saturation of the B-ring of non-classical, quinazoline antifolate inhibitors of thymidylatesynthase, analogues 7-17 were designed. Analogues 13-17
In one aspect, compounds having antiviral activity and having the general formula: ##STR1## wherein each R.sup.2, independently, is H or lower (fewer than 6 carbon atoms) alkyl; each R.sup.3, independently, is H or lower alkyl; R.sup.0 is H or lower alkyl; R.sup.1 is H or lower alkyl; 1.ltoreq.n.ltoreq.11; n-2.ltoreq.m.ltoreq.2n; 0.ltoreq.p.ltoreq.3; z is 0 or 1; and p.ltoreq.1.ltoreq.2p; each n, m, p, and q being selected so that the sp.sup.3 valence shell of each carbon atom in each ring is filled; or a pharmaceutically acceptable salt thereof.
