In this work the results of the reaction of β-alkoxyvinyl trihalomethyl ketones 1, 2a-e, with guanidine hydrochloride are reported. Depending on the ketone 1 or 2 and the conditions under which the reactions were carried out, 4-trihalomethyl-2-amino pyrimidines, β-alkoxyvinyl carboxylic acids, or β-acetal carboxylic esters were obtained.
