Abstract
The corresponding 2,3-diphenyl[3,2-a]pyrimidinium salts were obtained by the condensation of 4,5-diphenyl-2-aminothiazole perchlorate with β-diketones, β-chlorovinyl ketones, β-chlorovinyl aldehydes, and 1,1,3,3-tetraethoxypropane. The PMR spectra were used to prove the structures of the compounds obtained, particularly to select the structures of the isomeric salts obtained in the condensation with unsymmetrical β-diketones, β-chlorovinyl ketones, and β-chlorovinyl aldehydes. As a rule, the latter give one isomer — the γ-unsubstituted (relative to the bridge nitrogen atom) derivative.
