Abstract
In the presence of zinc chloride, the in situ generated β-enamino ester from the reaction of morpholine, piperidine and pyrrolidine with methyl propiolate reacted, with aromatic aldehydes and thiourea in ethanol resulting in the functionalized tetrahydropyrimidin-2-thiones in satisfactory yields and with good diastereoselectivity. When aromatic aldehydes bearing electron-withdrawing group were used in the reaction, the 4-hydroxytetrahydropyrimidin-2-thione derivatives were obtained as the main product.
