Aromatic thiourea derivatives were synthesized by standard reactions from isothiocyanates in high yield. An efficient one-pot synthesis of primary amine with carbon disulfide involving the intermediate dithiocarbamate conversion using T3P (propane phosphonic anhydride) to isothiocyanate is reported. Newly synthesized compounds showed excellent luminescence property. Cytotoxic investigation with different human cancer cell lines showed IC50 values varying from of 17 to 40 μM for N-phenethyl-3,4-dihydroisoquinoline-2(1H)-carbothioamide (SCR172) among other molecules. Increase in Sub G1 population and increased depolarisation of mitochondria were evident in cells treated with SCR172, suggesting its role as a cancer therapeutic agent. This provides a lead structure for further synthetic modifications.

An "on-water" one-pot process has been engineered for the preparation of 2-aminobenzothiazole from ortho-halo (-F, -Cl, -Br and -I) substituted unsymmetrical thioureas. For ortho -I and -Br substrates the reactions afford 2-aminobenzothiazoles under metal free condition promoted by base. However, the relatively inert ortho -Cl and -F substrates undergo intramolecular arylthiolation only in the presence of CuO nanoparticles yielding 2-aminobenzothiazoles. This methodology provides easy access to aminobenzothiazoles utilising even the ortho -Cl and -F substrates. The catalyst is recyclable several times without loss of substantial activity. Other remarkable features include the wide range of functional group tolerance, absence of chromatographic purification (for ortho -I and -Br substrates) and providing moderate to excellent yield of the products under mild conditions, thus rendering the methodology as a highly eco-friendly alternative to the existing methods.
