A series of 2-((arylamino)methyl)-5-(3-methoxyphenyl)-1-phenyl-1H-1,2,4-triazole-3-thione derivatives have been synthesized and characterized by FT-IR, NMR, mass spectral and elemental analysis. Compounds (MM4a-m) have been evaluated for their in vitro antibacterial activity against selected gram-positive and gram-negative bacteria and in vitro antifungal activity against fungal pathogens by us...

2-Furylcarbinols undergo a smooth aza-Piancatelli rearrangement followed by Friedel-Crafts alkylation with a bifunctional substrate, (1H-pyrrol-1-yl)aniline, in the presence of 10 mol% In(OTf)3 in acetonitrile at room temperature to afford the corresponding hexahydrobenzo[b]cyclopenta[f]pyrrolo[1,2-d][1,4]diazepin-11(4aH)-one scaffolds in good yields. This method offers significant advantages s...

In the present study, a new series of 2,6-diaryl-3-methyl-4-piperidones was synthesized by Mannich reaction (condensation) of ethyl-methyl ketone, substituted aromatic aldehydes and ammonium acetate. Oximes and thiosemicarbazone derivatives of 2,6-diaryl-3-methyl-4-piperidones were synthesized by reaction with hydroxylamine hydrochloride and thiosemicarbazide respectively. The chemical structur...

The reaction of 5-amino-3-(arylamino)-1H-pyrazole-4-carboxamides 1a,b with acetylacetone 2 and arylidenemalononitriles 5a-c yielded the pyrazolo[1,5-a]-pyrimidine derivatives 4a,b and 7a-f respectively. On the other hand, Schiff bases 9a,b and 12a-j were obtained upon treatment of carboxamides 1a,b with isatin 8 and some selected aldehydes 11a-e. The newly synthesized compounds were characteriz...

The crystal structure of the title compound, C(14)H(13)NO, exhibits an E configuration. The conjugated compound is slightly twisted with a dihedral angle of 29.3° between the benzene and pyrrole rings. Two inter-molecular C-H⋯O inter-actions lead to a dimer. In the crystal, intermolecular C-H⋯O interactions generate an inversion dimer.

The title compound, C16H12N2O, exists in the crystalline state as the 5-imino-3,4-di-phenyl--1H-pyrrol-2-one tautomer. The dihedral angles between the pyrrole and phenyl rings are 35.3 (2) and 55.3 (2)°. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds generate a graph-set motif of R 2 (2)(8) via N-H⋯N hydrogen bonds.

In the mol-ecule of the title compound, C(13)H(10)ClNO, the benzene and pyrrole rings are oriented at a dihedral angle of 7.37 (12)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. There are C-H⋯π inter-actions between benzene and pyrrole rings and a benzene C-H group. A weak π-π inter-action between the pyrrole rings...

The title compound, C(13)H(9)FN(2)O, a potential neuroprotective agent, consists of an indolinone and a pyrrolyl unit [dihedral angle between the ring planes = 4.9 (1)°]. An intra-molecular hydrogen bond between the carbonyl O atom and the NH group of pyrrole correlates with the Z arrangement of the substituents at the C=C bond. In the crystal, inversion dimers occur, linked by pairs of N-H⋯O b...
