Abstract
Three-component condensation of pyruvic acid with aromatic aldehydes and some aminoazoles was developed as a procedure for the synthesis 5-aryl-5,8-dihydroazolo[1,5-a]pyrimidine-7-carboxylic acids. An influence of solventtype on the composition of the reaction products was found. The structures of the compounds obtained were proved by 1 H and 1 3 C NMR spectroscopy, NOE experiments, and X-ray analysis.
