Abstract
Ethoxycarbonyl isothiocyanate has been found to form adducts with enamines which, on treatment with primary amines or ammonia, undergo apparent “amine exchange” and cyclization to 4-thiouracil derivatives. Evidence for the 4-thiouracil structure includes both spectral data and chemical transformations.
