Abstract:Peculiarities of the course of the methanesulfo-derivatives of (benzo)imidazo[2,1-b][1,3]thiazines reac-tions with a number of nucleophilic reagents were studied. It was determined that they react nonselectively with potassium thiocyanate to form a mixture of thio- and isothiocyanate derivatives. When interacting with sodium azide, nucleophilic substitution competes with an elimination reaction. The latter is dominant in the reaction with sodium cyanide. The spatial structure of one of the isomer elimination p… Show more
