title: Nitrogen bridgehead compounds, facile synthesis of bioactive cyanopyrimido[1,2-a]pyrimidinones.
abstract: Synthesis of some new cyanopyrimido[1,2-a]pyrimidinones 5-22 have been achieved via interaction of 2-amino-6-anisyl-5-cyano-4(3H)-pyrimidinone (1) with some heterocycles having a vicinal chloroester, chlorocyano or mercaptocyano group, dimethyl acetylenedicarboxylate, active methylene compounds, ethyl 2-acetyl-3-anisylpropenoate, ethyl 3-aryl-3-cyanopropenoates, ethyl 2-cyano-3-ethoxyacrylate and some enones or enals. Some of the isolated products were subjected to biological screening tests.
