An efficient and convenient synthesis of quinazoline derivatives catalyzed by cyanuric chloride in water
In this work, an eco-friendly procedure for the preparation of 2,3-dihydroquinazoline-4(1H)-ones was developed by condensation reaction of benzylic and heterocyclic aldehydes with 2-aminobenzamide in the presence of catalytic amounts of cyanuric chloride (2,4,6-trichloro-1,3,5-triazin) as an available and inexpensive organo-catalyst under aqueous media as a green conditions. The new co...

Multi-component coupling reaction (MCR) is a powerful synthetic tool for the synthesis of biologically active compounds. Development of such multi-component coupling reaction strategies in visible light has been of considerable interest, as they provide simple and rapid access to a large number of organic molecules through a sustainable path. An efficient and green protocol for the synthesis of...
متن کاملEfficient carbonate synthesis under mild conditions through cycloaddition of carbon dioxide to oxiranes using a Zn(salphen) catalyst.
Zn(salphen) complexes are reported as effective, cheap, robust and relatively green catalysts for the cycloaddition of carbon dioxide to terminal epoxides to afford cyclic carbonates in good yields.
