Description | Several research workers investigated the S / N nucleophilic character competition of the thioamide moieties (included in cyclic and acyclic systems) by the intermolecular reaction with electrophiles. The discrimination between the S-alkylation and the N-alkylation were briefly published for several cases but the reason for N- and S-atoms contributions were not yet described. Our communication will simply explain the N- and S-atoms involvement in reactions on the model compound 4-methyl-1-thioxo-1,2,4,5-tetrahydro[1,2,4]triazolo[4,3-a]quinazolin-5-one. |
