The synthesis of (S)-(-)-limonene derivatives containing (1H-1,2,3-triazol-4-yl)methyl 4-bromobenzoate were obtained by epoxidation, azidolysis and Huisgen’s 1,3-dipolar cycloaddition. Two products were isolated and characterized by FT-IR, ¹H NMR, ¹³...

We report herein the synthesis of 1,1,2,2-tetrakis[(benzoylamino)methyl]-hydrazine from (benzamidomethyl)triethylammonium chloride and hydrazine monohydrate in the presence of triethylamine in ethanol/aqueous media. The structure of the newly synthes...

The title compound 2-[(3,5-dimethyl-1-phenyl-1H-pyrazol-4-yl)methylene]-indane-1,3-dione (3) was synthesized in high yield by reaction of 3,5-dimethyl-1-phenyl-pyrazole-4-carbaldehyde and indane-1,3-dione in ethanol in the presence of pyridine. The s...

Iodine-catalyzed cyclocondensation of cinnamaldehyde and thiophenol yields rapidly trans-2-phenyl-4-thiophenoxy-3,4-dihydro-2H-1-benzothiopyran in excellent yield with very high diastereoselectivity.

In this short note, we report the synthesis of 6-methyl-2-nitro-1-phenyl-hept-4-en-3-ol by a LiAlH₄ catalyzed nitroaldol reaction for carbon-carbon bond formation. The title compound was characterized by ¹H-NMR, ¹³C-NMR, MS, IR and elemental analysis.

7-Phenyl-3,4,8,9-tetrahydro-2H-pyridazino[1,6-a][1,3,5]triazin-2-imine was synthesized by a sequence of reactions starting from 6-phenyl-4,5-dihydropyridazin-3(2H)-one 1. The structure of the title compound 3 was established on the basis of IR, ¹H-NM...

The copper complex of 5,10,15,20-Tetra(N-ethyl-3-carbazolyl) porphyrin was synthesized and characterized by electronic absorption spectrophotometry and cyclic voltammetry. The spectral data were in agreement with the proposed structure. The copper co...

(Benzoylamino)methyl 4-acetyloxybenzoate (3) was obtained in a reaction of benzamidomethylation of 4-acetyloxybenzoic acid (2) with (benzamidomethyl)­triethyl­ammonium chloride (1).

A novel pyrazoline derivative 2 was synthesized by reaction of an α,β-unsaturated ketone 1 with isonicotinic acid hydrazide (INH) in glacial acetic acid. The structure of the title compound 2 was established on basis of IR, ¹H-NMR, ¹³C-NMR and mass s...

The title compound, (2E)-1-(2,5-dimethyl-3-thienyl)3-(4-nitrophenyl)propenone (3) was synthesized in high yield by reaction of 3-acetyl-2,5-dimethythiophene and 4-nitrobenzaldehyde in the presence of sodium hydroxide. The structure of the compound wa...

In this note, two procedures for the synthesis of (benzoylamino)methyl 4-[(benzoylamino)­methoxy]benzoate (3) are presented. The first procedure is carried out in dioxane/water using benzoylaminomethyl-4-hydroxybenzoate, while the second one employs...

Methylparabene (2) was simply benzamidomethylated with (benzamidomethyl)­triethylammonium chloride (1) in aqueous medium to afford methyl 4-(benzamido­methoxy)benzoate (3) in high yield. The title compound was characterized by elemental analysis, FT-...
