A regioselective [2+3] cyclocondensation between chlorocarbonylsulfenyl chloride (3) and 2-aminobenzothiazoles gave 3H-1,2,4-thiadiazolo[3,4-b]benzothiazol-3-ones (1). Some heterocycles (1) and their isosteric known 5-substituted 2-methyl-imidazo[2,1-b]benzothiazoles (2) which were prepared from 2-aminobenzothiazoles via two steps, showed significant fungicidal activities.

The FeCl3/ZnI2-catalyzed aerobic oxidative cyclization between 2-aminobenzothiazole and ketone/chalcone for the synthesis of benzo[d]imidazo[2,1-b]thiazole is described. A variety of fused benzoimidazothiazole derivatives are obtained by this protocol.

N-Methyl-2-phenylimidazole (Ph-NMI) and 2-phenylimidazo[2,1-b]benzothiazoles (Ph-IBT) catalyzed selective acylation of primary alcohols using acid anhydrides. The Ph-NMI- or Ph-IBT-catalyzed reaction using (PhCO)2O as an acylating agent could particularly acylate the primary hydroxy group of 1,n-diols (n ≥ 3) with a high, synthetically useful selectivity.

The reaction of 2-imino-3-(2-propynyl)-1,3-benzothiazole with various iodobenzenes in the presence of a palladium catalyst leads to the production of 2-benzylimidazo[2,1-b][1,3]benzothiazoles.
