; ; ; ; ; ;

Isoflavones and their thiazole and pyrazole analogs are recyclized into the corresponding 4-(2-hydroxyphenyl)-pyrimidine derivatives under the effect of amidines. Their PMR spectra were studied. The effects related to the formation and strength of the intramolecular hydrogen bond were examined.
