Abstract

V originále

The model N3,N3-(3-oxapentan-1,5-diyl)-N1-(2-phenyl-3,4-dihydro-quinazolin-4-yliden)thiourea 1 reacts with phenacyl bromides to afford N4-(5-aryl-1,3-oxathiol-2-yliden)-2-phenylquinazolin-4-amines orN4-(4,5-diphenyl-1,3-oxathiol-2-yliden)-2-phenyl-4-aminoquinazoline by a kinetically controlled reversible reaction favoring the enolate reaction intermediate, while the 4-[4-aryl-5-(2-phenylquinazolin-4-yl)-1,3-thiazol-2-yl]morpholine was produced by a thermodynamically controlled reversible reaction favoring the C-anion intermediate. The reaction of 1 with chloroacetic acid derivatives gave 4-substituted-2-morpholino-5-(2-phenyl-quinazolin-4-yl)-1,3-thiazoles as the only reaction pathway.
