Abstract

KF/clinoptilolite nanoparticles were used as an effective heterogeneous catalyst for the synthesis of spiro[indole-3,2'-pyran] derivatives via three-component reactions of N-alkylisatins, 1,3-dicarbonyl compounds, and electron-deficient acetylenic compounds under solventfree conditions at 80°C. The present protocol has significant advantages, such as high yields, easy purification, and low environmental impact. [ABSTRACT FROM AUTHOR]

Abstract

Thiomethylene-active derivatives of N-imidazolylimines undergo intramolecular cyclization to give 3,4-dihydro-2H-imidazo[2,1-b][1,3,4]thiadiazines. This reaction is a new convenient method for the fusion of a dihydrothiadiazine ring to an imidazole fragment through formation of a C-C bond. [ABSTRACT FROM AUTHOR]
