Synthesis of 5-Amino and 3,5-Diamino Substituted 1,2,4-Thiadiazoles by I2-Mediated Oxidative N-S Bond Formation
An oxidative N-S bond formation reaction has been established for 1,2,4-thiadiazole synthesis employing molecular iodine as the sole oxidant. The features of the present reaction include no use of transition metals, mild reaction conditions, simple operat
Studies on Amidinothioureas as New Precursors of 2,4-Diaminothiazoles
Interaction of several amidinothioureas, R'NHC(=NR'')NHCSNHR, with phenacyl bromide has been investigated as a new route to 5-benzoyl-2,4-(disubstituted-amino)thiazoles.The effect of different substituents on the amidino function of the amidinothiourea up
