A copper-based catalytic system has been developed to enable formal [3 + 1 + 2] annulations of ketoxime acetates, aldehydes, and cyanamides. This protocol offers a new strategy for the synthesis of highly substituted 2-aminopyrimidine compounds, and more importantly, pyrimidines have now been included in the N-heterocycle family constructed usingO-acyl ketoximes as N-C-C synthons.

2-Arylidene-1-tetralones (I) were condensed with benzamidine or guanidine to give the corresponding substituted benzoquinazolines II and III, respectively.The structures of all products were established by chemical and spectroscopic methods.
