Abstract

The cyclo condensation of some bi-functionally quinazolinones with some phosphorus dihalides in dry pyridine led to novel 1,3,4,2-oxadiazaphospholo[5,4-b]quinazolinones, 1,3,4,2-thiadiazaphospholo[5,4-b]quinazolinones and 1,2,4,3-triazaphospholo[5,1-b]quinazolinones. The structure of novel products was established by IR and NMR spectroscopy.
