Synthesis and surface active properties of condensed and non-condensed quinazoline derivatives of industrial application

A number of novel quinazolines and annulated quinazolines 4-11 are obtained via the nucleophilic interaction of 2-alkyl-4H-3,1-benzoxazin-4-one 3 with different nitrogen nucleophiles. Hydrazinoquinazoline 11 is used for the synthesis of other quinazoline derivatives 12-14 through the reaction of different reagents. The antimicrobial, surface active properties and the biodegradability of some of the synthesized compounds are described.
