چکیده
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.

Benzotiazole and pyrimidine have been reported to act as effective pharmacophores. However, much less work as been carried out on these heterocycles fused with each other. In the present study, we report the synthesis of a series of 8-chloro-3(phenylcarbonoimidoyl)-10a-H-pyrimido [2,1-b][1,3]benzothiazole-2-thiol. This series was synthesized by the reaction of 8-chloro-2-sulfanyl-10a-H-pyrimido...
متن کاملBrønsted acidic ionic liquid ([BMIm]HSO4) as an efficient catalysts for the one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives
The Brønsted acidic ionic liquid ([BMIm]HSO4) catalyzed three-component synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives at room temperature. The integrity of the ionic liquid remains reasonably unchanged when it is separated from the reaction mixture by water extraction, as it can be recycled several times without any loss of activity in each of the title syntheses. The products a...
