A variety of novel 2-alkylthiopyrimidines were synthesized through simple condensation of arylidenemalononitriles with different 2-alkylthiouronium halide derivatives catalyzed by anhydrous potassium carbonate (K2CO3). The reactions have been carried out under mild conditions in i-PrOH, and the products were obtained in moderate to good yields with a simple work-up method. Subsequently, some examples of these compounds have been converted into Tacrine analogs by applying the Friedl?nder reaction.
Clean and economic synthesis of alkanesulfonyl chlorides from S-alkyl isothiourea salts via bleach oxidative chlorosulfonation

, p. 225 - 229 (2014/03/21)
A simple procedure for clean and economic synthesis of alkanesulfonyl chlorides via bleach-mediated oxidative chlorosulfonation of S-alkyl isothiourea salts is disclosed. This procedure is environment- and worker-friendly with the advantages of readily accessible materials and reagents, simple and safe operations, easy purification without chromatography, and affords high yields of up to 99%.
