A simple, green and high-yielding procedure for the synthesis of 4-substituted-2-(alkylsulfanyl)thiazoles from the reaction of dithiocarbamates and α-halocarbonyl containing compounds in water is described. Also, a one-pot, two-step procedure for the synthesis of 2-(alkylsulfanyl)thiazoles from acetophenone and dithiocarbamates was developed.
Synthesis of <i>N</i>,<i>S</i>-Heterocycles and Dithiocarbamates by the Reaction of Dithiocarbamic Acids and <i>S</i>-Alkyl Dithiocarbamates with Nitroepoxides
A facile and efficient procedure for the synthesis of substituted thiazole-2(3H)-thiones and thiazolidine-2-thiones by the reaction of primary amines, carbon disulfide, and nitroepoxides is described. By using secondary amines in this protocol, the corresponding dithiocarbamate-substituted phenyl-2-propanones were prepared in excellent yields. In addition, substituted thiazoles and 1-(alkylthio)-1
The synthesis of α-dithiocarbamato-alkyl-β-naphthols is reported via the Betti reaction of naphthols, aldehydes and ammonia-based dithiocarbamates in the presence of ZnCl2 undersolvent-freeconditions. High to excellent yields and simple reaction conditions are the main advantages of this reaction.
