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...

متن کاملSynthesis of novel dopamine derived multidirectional ligands from cyanuric chloride: structural and antimicrobial studies
Two monopodal (2,4-dichloro-6-(3-hydroxytyramine)-1,3,5-triazine) and tripodal (2,4,6-(3-hydroxytyramine)-1,3,5-triazine) s-triazine derivatives were prepared through the reaction of cyanuric chloride (2,4,6-trichloro-1,3,5-triazine) and 3-hydroxytyramine hydrochloride (dopamine hydrochloride). The structures of the compounds were identified by FT-IR, 1H NMR, 13C NMR, thermal analysis and eleme...
متن کاملMild and efficient cyanuric chloride catalyzed Pictet–Spengler reaction
A practical, mild and efficient protocol for the Pictet-Spengler reaction catalyzed by cyanuric chloride (trichloro-1,3,5-triazine, TCT) is described. The 6-endo cyclization of tryptophan/tryptamine and modified Pictet-Spengler substrates with both electron-withdrawing and electron-donating aldehydes was carried out by using a catalytic amount of TCT (10 mol %) in DMSO under a nitrogen atmosphe...
متن کاملEfficient conversion of nitronate into nitrile oxide using cyanuric chloride. One-pot synthesis of bicyclic isoxazolines and isoxazoles from nitroalkenes.
Bicyclic isoxazolines and isoxazoles are obtained in good yields by proceeding through a convenient one-pot, two-step procedure utilizing 2,4,6-trichloro-1,3,5-triazine (TCT) as a dehydrating agent.
