Yu, Fuchao published the artcileThree-component solvent-free synthesis of highly substituted tetrahydroimidazo[1,2-a]pyridines, Recommanded Product: 1,2-Dimethoxy-4-(2-nitrovinyl)benzene, the publication is RSC Advances (2011), 1(4), 596-601, database is CAplus.
An efficient and green method was developed for the synthesis of tetrahydroimidazo[1,2-a]pyridines by three-component reactions of heterocyclic ketene aminals, triethoxymethane, and nitro alkenes in one-pot in the absence of catalyst and solvent. This protocol has advantages of environmental friendliness, high yields (73-93%), short reaction time and convenient operation.
RSC Advances published new progress about 4230-93-7. 4230-93-7 belongs to catalysis-chemistry, auxiliary class Alkenyl,Nitro Compound,Benzene,Ether, name is 1,2-Dimethoxy-4-(2-nitrovinyl)benzene, and the molecular formula is C7H5ClN2S, Recommanded Product: 1,2-Dimethoxy-4-(2-nitrovinyl)benzene.
