Treatment of nucleophilic heterocycles like pyrroles and thiophenes, and their tetrahydro derivatives, with S2Cl2 and DABCO in chloroform at room temperature provides a simple one-pot synthesis of fused mono and bispentathiepins. N-Methylpyrrole and its 2-chloro and 2,5-dichloro derivatives and N-methylpyrrolidine all give the same dichloropentathiepin 1a.(More)
Novel 6-cyanoindolo[3,2-c]quinoline and 6-cyanobenzimidazo[1,2-c]quinazoline derivatives have been synthesised by treatment of the appropriate aromatic amines with 4.5-dichloro-1,2,3-dithiazolium chloride 1 (Appel salt). The cytotoxicity and the effect of these compounds on cellular growth were measured.
