چکیده

In the title compound, C(14)H(8)Br(2)F(3)NO, the mol-ecule is disordered across an approximate non-crystallographic mirror plane, which is in the plane of the fused ring system [The tetrahedral C atom bearing the trifluormethyl substituent is disordered with site occupancy factors of 0.80 (2) and 0.20 (2)]. In the crystal, a one-dimensional stacking of mol-ecules involves inter-actions between the pyridine ring and symmetry-related Br and O atoms of adjacent mol-ecules. The stacking distance between the mean planes of adjacent mol-ecules is 3.395 (4) Å.

Design, synthesis and anticonvulsant activity of some new 5,7-dibromoisatin semicarbazone derivatives

A series of 5,7-dibromoisatin semicarbazones have been synthesized in good yield, involving aryl urea and aryl semicarbazide formation. The structures of the synthesized compounds were confirmed on the basis of their spectral data. All the compounds were evaluated for anticonvulsant and CNS depressant activities. Anticonvulsant activity was determined after intraperitoneal (i.p.) administration...

2-Hy­droxy-2-trifluoro­methyl-3,4-dihydro-2H-1-benzopyran-4-one

The heterocyclic ring in the title compound, C(10)H(7)F(3)O(3), has a half-boat conformation with the hy-droxy-bearing C atom lying 0.595 (3) Å out of the plane of the five remaining atoms (r.m.s. deviation = 0.022 Å) in the direction of the hy-droxy O atom. Linear supra-molecular chains along the a axis, sustained by O-H⋯O hydrogen bonds between the hy-droxy H and ketone O atoms, feature in th...

Isolation and structure elucidation of a new prenylcoumarin from Murraya paniculata var. omphalocarpa (Rutaceae).

A new C-8 prenylated 5,7-dimethoxycoumarin named omphamurrayin was isolated from the leaves of Murraya paniculata var. omphalocarpa, and its structure was established as 5,7-dimethoxy-8-(1-oxo-2-senecioyl-3-methyl-3-butenyl)-2H-1-benzopyran-2-one on the basis of the spectroscopic evidence. The taxonomic status of M. paniculata var. omphalocarpa is briefly discussed, along with its synonymity to...
