The reactions of hexafluoroacetone and methyl trifluoropyruvate acyl- and ethoxycarbonylimines with benzamidines afford fluoro containing heterocycles of four structural types: dihydrotriazines, dihydrotriazinones, imidazoles, and imidazooxazoles.

Previously unknown fluorinated α-alkoxy(aryloxy)alkylisocyanates, the esters of α-alkoxy and α-aryloxy-2-isocyanato-3,3,3-trifluoropropionic acids, were obtained. The synthetic potential of these compounds were demonstrated in reactions with anilines leading to 2-substituted 3,3,3-trifluoroalanine derivatives.
