Abstract
Dialkyl-2-(dialkoxyphosphonyl)-3-(1,6-dihydro-6-oxo-4-propylpyrimidin-2-ylthio) succinates and dialkyl-2-(dialkoxyphosphonyl)-3-(1,6-dihydro-6-oxopyrimidin-2-ylthio) succinates were synthesized in moderate to high yields using a novel, facile, and one-pot condensation of dialkyl acetylenedicarboxylates, trialkylphosphites, and thiouracil derivatives.
