, p. 5819 - 5834 (2007/10/02)
3,4-D-Dihydroquinazolines and Quinazolines were prepared starting from N'-aryl-N-(triphenylphosphoranilidene)-carboximidamides and aliphatic or aromatic aldehydes. The mechanism of the reaction is discussed.

N-imidoyliminotripheny]phosphorane reacts with aliphatic and aromatic aldehydes to give via an 1,3-diaza-1,3-diene intermediate 3,4-dihydro quinazolines and quinazolines. The ratio between the reaction products depends from the aldehyde employed.
