A novel symmetrical bisamine derivative (4) was synthesized by condensation reaction of 2,2'-thio-bis[4-methylphenol] (1) and isatoic anhydride in acetonitrile as solvent in the presence of K₂CO₃ under reflux conditions. The structure of the title co...

The title compound 1 was synthesized by the coupling reaction of 2,3,4,6-tetra-O-benzyl-1-C-phenyl-α-D-glucopyranose (2) with 2,3,4,6-tetra-O-benzyl-D-glucopyranose (3) in the presence of 5 mol% bismuth(III) triflate in dichloromethane at 0 °C.

3-(1H-Indol-3-yl)-4-(morpholin-4-yl)cyclobut-3-ene-1,2-dione was obtained in good yields (72–82%) by nucleophilic substitution of 3-chloro-4-(1H-indol-3-yl)cyclobut-3-ene-1,2-dione with morpholine.

A new Schiff base ester, 4-{[(4-chlorophenyl)imino]methyl}-3-hydroxyphenyl 4-(hexadecanoyloxy)benzoate was synthesized and its IR, ¹H-NMR, ¹³C-NMR and MS spectroscopic data are presented.

A simple and novel route for synthesis of new spirocyclic compound is developed. The present work involves condensation of ethyl nipecotate with 2-furaldehyde followed by the MnO₂ oxidation to give the β-keto ester which upon reaction with hydrazine...

Novel 7-{[2-(4-hydroxyphenyl)methylidene]amino}-1,3-thiazol-4-yl)-2-(methoxyimino)acetyl]amino}-3-{[(2-methyl-5,6-dioxo-1,2,5,6-tetrahydro-1,2,4-triazin-3-yl)sulfanyl]methyl}-8-oxo-5-thia-1azabicyclo [4.2.0]oct-2-ene-2-carboxylic acid was prepared by...

A new Schiff base ester, 4-{[(4-bromophenyl)imino]methyl}-3-hydroxyphenyl 4-(hexadecanoyloxy)benzoate was synthesized and its IR, ¹H NMR, ¹³C NMR and MS spectroscopic data are presented.

The title compound, N,N’-bis-(2,5-dimethyl-3-oxo-1-phenyl-2,3-dihydro-1H-pyrazol-4-yl)phthalamide has been synthesized by reactions of o-phthaloyl chloride with 4-amino-2,5-dimethyl-1-phenyl-3-oxo-1H-pyrazolone in acetonitrile. The structure of the n...

Methyl 6-methyl-1-(4-methylphenyl)-2-oxo-4-phenyl-1,2,3,4-tetrahydro-pyrimidine-5-carboxylate has been synthesized via the modified Biginelli reaction from benzaldehyde, p-tolylurea, and methyl acetoacetate, promoted with microwave irradiation and ca...
