Stable crystalline phosphorus ylides were obtained in excellent yields from the 1:1:1 addition reaction between triphenylphosphine and dialkyl acetylenedicarboxylates presence of strong NH-acids, such as benzotriazole, 5-methylbenzotriazole, 5-chlorobenzotriazole, pyrrole, 2-acetylpyrrole, pyrrole-2-carboxaldehyde, 4-nitro-acetanilide, 4-methoxyacetanilide, 4-bromoacetanilide, 4-methylacetanilide, 2-methyl-acetanilide, 2,6-dimethylacetanilide. These stable exist a solution mixture two...
Stable crystalline phosphorus ylides were obtained in excellent yields from the 1:1:1 addition reaction between triphenylphosphine and dialkyl acetylenedicarboxylates, presence of strong NH-acids, such as imidazole, 2-methylimidazole, 4-methylimidazole, 2-ethylimidazole, benzimidazole, 5,6-dimethylbezimidazole. These stable exist solution a mixture two geometrical isomers result restricted rotation around carbon–carbon partial double bond resulting conjugation ylide moiety with adjacent...
A simple and efficient method was developed for one-pot, five-component synthesis of highly functionalized piperidines from reactions β-keto esters, aromatic aldehydes, various amines catalyzed in acetic acid medium. The reaction proceeded smoothly to generate the corresponding product good yield. We have found that use as medium has a remarkable beneficial effect on reaction, allowing it be performed without need incorporate catalyst, which is case other similary reported methodologies. In...
Abstract α‐Amino phosphonates were obtained in a one‐pot, simple, and efficient method from the reaction between aldehyde, aniline, trialkyl phosphite, silica sulfuric acid as catalyst acetonitrile at room temperature. © 2009 Wiley Periodicals, Inc.

This work focused on the effects of temperature and different <italic>para</italic>-substituted anilines activation parameters kinetics synthesis reaction 3,4,5-substituted furan-2(5<italic>H</italic>)-ones which were studied spectrally at temperatures in formic acid.
A simple synthesis of N-aryl-3-aminodihydropyrrol-2-one-4-carboxylates via one-pot multi-component reaction amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence oxalic acid dihydrate (20 mol%) as catalyst methanol is described. This homogeneous catalytic procedure offers advantages including mild conditions, good to high yields, short time, readily available starting materials, easy work-up there no need for column chromatography.
Stable crystalline phosphorus ylides were obtained in excellent yields from the 1:1:1 addition reaction between triphenylphosphine and dialkyl acetylenedicarboxylates, presence of strong NH-acids, such as pyrazole, indazole 5-nitro Indazole. These stable exist solution a mixture two geometrical isomers result restricted rotation around carbon–carbon partial double bond resulting conjugation ylide moiety with adjacent carbonyl group.
Abstract Stable crystalline phosphorus ylides were obtained in excellent yields from the 1:1:1 addition reaction between triphenylphosphine and dialkyl acetylenedicarboxylates, presence of NH‐acid, such as 3,6‐dibromocarbazole. These stable exist solution a mixture two geometrical isomers result restricted rotation around carbon–carbon partial double bond, resulting conjugation ylide moiety with adjacent carbonyl group. To determine kinetic parameters reactions, they monitored by UV...
