Abstract
One-step ring-annulation of 5-substituted 2-amino-2-oxazolines with diethyl ethoxymethy-lenemalonate yielded 2-substituted 6-carboethoxy-2,3-dihydro-5H-oxazolo[3,2-a]pyrimidin-5-ones. Under the same conditions 2-substituted 6-cyano-2,3-dihydro-5H-oxazolo[3,2-a]-pyrimidin-5-ones and the corresponding 2-ethyl(methylenecyanoacetate)-2-iminooxazo-lidines were obtained from ethyl ethoxymethylenecyanoacetate. Some of these compounds were evaluated in mice for antiparasitic activity.
