1BF_3·OEt_2 Promoted Solvent-free Synthesis of Benzimidazole Derivatives显示文摘Differently substituted benzimidazoles have been synthesized in very good yields in solvent-free conditions from o-phenylenediamine and aldehydes in the presence of BF3·OEt2 as a catalyst. The method is applicable to aromatic, unsaturated and aliphatic aldehydes and to substituted o-phenylenediamines without significant differences.Rahul R.NAGAWADE Devanand B.SHINDE 2006Chinese Chemical Letters2006,17,4:2
2Zirconyl Chloride Promoted Highly Efficient Domino Synthesis of New 1, 2, 3, 4-Tetrahydroquinoline Derivatives in Water显示文摘The tetrahydroquinoline moiety is a structural feature of many natural products. By using a domino reaction of aromatic amines and cyclic enol ethers catalyzed by zirconyl chloride in water, various tetrahydroquinoline derivatives were synthesized efficiently. Most cyclized products showed cis selectivity. The cis selectivity was tentatively rationalized due to chelation control in water.Rahul R.NAGAWADE Devanand B.SHINDE 2006Chinese Chemical Letters2006,17,9:1
