Notes:
The 13C NMR spectra of sixteen isomeric 2-and 4-alkoxycarbonylalkylthiouracils, eightnew 2,4-dialkoxycarbonylalkylthiouracils and eight isomeric 3-oxothiazolo[3,2-a]-and 3-oxothiazolo[3,2-c]-pyrimidin-5-ones have been calculated and fullyassigned. The AiK empirical parameters of the 2-thio, 4-thio, 6-methy1, 2-alkoxycarbonylalkylthio, 4-alkoxycarbonylalkylthio, P-alkoxycar-bonylalkyl, 4-alkoxycarbonylalkyl, N-3-carbonylalkylthio-2-, N-3-carbonylalkylthio-4, N-3-carbonylalkyl-2-thio and N-3-carbonylalkyl-4-thio groups were calculated for the predictions of the chemical shifts of substituted uracils.
