A new Schiff base ether, p-n-(dimethylamino)benzylidene-p-dodecyloxyaniline, was synthesized and its IR, ¹H NMR, ¹³C NMR and MS spectroscopic data are reported.

A new C^α-tetrasubstituted α-amino acid rac-tert-butyl°3-(benzyloxycarbonylamino)-2-(4-bromophenyl)-tetrahydrofuran-3-carboxylate was synthesized and characterized by NMR, MS, elemental analysis and X-ray

3-Hydrazino-3-oxo-N-(4-sulfamoylphenyl)propanamide has been used as a synthon for the preparation of 3-[2-(4-chlorobenzylidene)hydrazino]-3-oxo-N-(4-sulfamoylphenyl)propanamide

An unexpected product, 1-[(2-oxonaphthalen-1(2H)-ylidene)methyl]urea 4 of the condensation reaction of 2-hydroxy-1-naphthaldehyde with or without ethyl benzoylacetate and urea under hydrochloric acid-catalyzed and solvent-free conditions is reported.

Two new C^α-tetrasubstituted α-amino acids (2R,3S)-((1R,2S,5R)-2-isopropyl-5-methylcyclohexyl) 2-(4-bromophenyl)-3-(tert-butoxycarbonylamino)-tetrahydrofuran-3-carboxylate and (2S,3R)-((1R,2S,5R)-2-isopropyl-5-methylcyclohexyl) 2-(4-bromophenyl)-3-(te...

We found the following error in our paper published in Molbank a few years ago [1]. The correct title should be: 2,2'-Dihydroxybenzophenone N-Carbonylethoxyhydrazone. [...]

We found the following error in our paper published in Molbank recently [1]. In the Scheme the positive charge should be at the nitrogen atoms and the negative charge should be at the chlorine atoms. The correct Scheme is shown below: [...]

A new Schiff base 4-[(pyridin-3-ylmethylene)amino]phenyloctadecanoate was synthesized and its IR, ¹H NMR, ¹³C NMR and MS spectroscopic data are presented.

Regioselective N-alkylation of 4-chloro-2-methoxy-7H-pyrrolo[2,3- d]pyrimidine (6) with ethyl 3-bromopropionate under liquid-liquid phase-transfer reactionconditions gave the ester 7a. Its saponification yielded the acid 7b. The logP values of a seri...

From time to time, the Publisher and the Editor-in-Chief of MolBank are asked the question: “what is the purpose of publishing a journal like MolBank?” We think that the start of a new year is a good opportunity to make the ideas behind such a journa...

A new Schiff base 4-[(pyridin-3-ylmethylene)amino]phenylhexadecanoate was synthesized and its IR, ¹H NMR, ¹³C NMR and MS spectroscopic data are presented.

A new Schiff base 4-[(pyridin-3-ylmethylene)amino]phenyltetradecanoate was synthesized and its IR, ¹H NMR, ¹³C NMR and MS spectroscopic data are presented.

Novel 3-hydrazino-3-oxo-N-(4-sulfamoylphenyl)propanamide has been efficiently synthesized from DEM and hydrazine hydrate. The synthesized hydrazide was screened for anti-tubercular activity.

A simple and novel route to the synthesis of imidazopyridines was developed. The present work involves the synthesis of 6-bromo-2-(3,4-dichlorophenyl)imidazo[1,2-a]pyridine (3) by using microwave irradiation. The synthesized compound (3) was well cha...

Donor-acceptor (D-p-A) dyestuff and colorants represent a vast majority of organic chromogens

The present work describes the synthesis of a Schiff base, 3-{4-[4-(benzylideneamino) benzenesulfonyl]phenyl}-2-phenylquinazolin-4(3H)-one from a novel quinazolinone, 3-[4-(4 aminobenzenesulfonyl)phenyl]-2-phenylquinazolin-4(3H)-one. The quinazolinon...
