Abstract
In the presence of trifluoracetic acid on the basis of three-component condensation of thiourea with its different aldeyhde (benzaldehyde, p-tolylaldehyde and acetaldehyde) and β-diketones (diethyl malonate, acetylacetate, ethyl acetoacetate, ethyl 2-ethylacetoacetate, 2-ethyl acetoacetate) an efficient method for the synthesis of tetra(hexa) hydropyrimidinethione- carboxylates has been worked out.
