Synthesis, spectroscopic (NMR and FT-IR) and theoretical (HF and DFT) investigation of dimethyl (Z)-2-[(2-methyl-5-oxo-1-cyclopentyl)oxy]-2-butendioate
Volume 5, Issue 4, pp. 364-493, Serial No. 17 , October 2017, , Pages 449-470
Abstract
Dimethyl (z)-2-[(2-methyl-5-oxo-1-cyclopentyl)oxy]-2-butenedioate has been synthesized using one-pot three component reaction between N-isocyaniminotriphenylphosphorane (Ph3PNNC), 3-methylcyclopentene-1,2-dione and dimethyl acetylenedicarboxylate. Also, optimized geometry and nuclear magnetic resonance ...

One-pot, four-component synthesis of fully substituted 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane (Ph3PNNC), a primary amine, a carboxylic acid and cinnamaldehyde
Volume 4, Issue 2, pp. 133-235, Serial No. 11 , April 2016, , Pages 155-164
Abstract
The imine intermediate generated by the addition of primary amine to the cinnamaldehyde is trapped by the N-isocyaniminotriphenylphosphorane (Ph3PNNC) and a carboxylic acid, and leads to the formation of the corresponding iminophosphorane intermediate. The 1,3,4-oxadiazole derivatives are formed via ... Read More)
The three-component reaction of 2-(2-oxopropyl)isoindoline-1,3-dione with alkyl isocyanides and aromatic carboxylic acids under catalyst-free conditions in water
Volume 4, Issue 1, pp. 1-132, Serial No. 10 , January 2016, , Pages 42-56
Abstract
A green and convenient protocol is described for the preparation of 1-(alkylamino)-3-(1,3-dioxoisoindolin-2-yl)-2-methyl-1-oxopropan-2-yl benzoates via one-pot three-component reaction between 2-(2-oxopropyl)isoindoline-1,3-dione, an alkyl isocyanide and an aromatic carboxylic acid in water at room temperature. ...

Preparation of sterically congested 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane, aromatic acids, cyclopentanone and primary amines
Volume 3, Issue 4, pp. 283-387, Serial No. 9 , October 2015, , Pages 310-322
Abstract
Reactions of N-isocyaniminotriphenylphosphorane with cyclopentanone have been studied in the presence of aromatic carboxylic acids and primary amines, proceeds smoothly at room temperature under neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives by an intramolecular Aza-Wittig ...

Ammonium nitrate as an efficient and green reagent for the oxidation of alcohols into their corresponding carbonyl compounds in the presence of heteropoly acids
Volume 3, Issue 2, pp. 72-147, Serial No. 7 , April 2015, , Pages 121-131
Abstract
Simple, cheap and green protocol for effective conversion of alcohols to corresponding carbonyl compounds in the presence of H14[NaP5W30O110] and ammonium nitrate is reported. The products were characterized by FT-IR and comparison of their physical properties with those reported in the literatures. ... Read More)
