ABSTRACT: The one-pot three-component reaction of 2-aminobenzothiazole, benzaldehyde derivatives and β-ketoester, β-diketone or malonate derivatives in solvent-free conditions provides the corresponding pyrimido [2,1-b] benzothiazole derivatives at 60?C in 60% - 72% yields without using any catalyst in an optimistic time.
