چکیده
THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: 4-acetyl-3-(4-meth-oxy-phen-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(11)H(10)N(2)O(4), contains four crystallographically independent mol-ecules. The 1,2,3-oxadiazole rings are almost planar [maximum deviations = 0.006 (3), 0.006 (3), 0.002 (3) and 0.009 (3) Å] and form dihedral angles of 55.03 (14), 61.02 (13), 58.36 (14) and 53.79 (15)° with their attached benzene rings. In the crystal, inter-molecular C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules, forming sheets parallel to (011).

In order to have antibacterial, analgesic and anti-inflammatory activity in the same molecule, 4-[1-oxo-3- (substituted aryl)-2-propenyl]-3-(4-chlorophenyl) sydnones were synthesized by condensing 4-acetyl-3-(4-chlorophenyl)sydnone with various substituted aryl aldehydes and characterized by spectral studies; 4-acetyl-3-(4-chlorophenyl)sydnone itself, was prepared by acetylation of 3-(4-chlorop...
متن کاملFisher Title : Bismuth Triflate Catalyzed Friedel - Crafts Acylations of Sydnones Date : June 2005
In the present work, suitably functionalized arylsydnones were used to synthesize a variety of 4-acyl-sydnones and diacyl sydnones, both as potential precursors to novel sydnoquinolines. The approach to the diacyl species is based on the discovery that activated sydnones brominate in both the 4 position of the sydnone ring and on the phenyl ring. Thus, it seemed likely that Friedel-Crafts react...

Sydnones, which contain a mesoionic five-membered heterocyclic ring, are more stable if synthesized with an aromatic substutuent at the N3 position. In the title compound {sys-tematic name: 4-acetyl-3-[2-(eth-oxy-carbon-yl)phen-yl]-1,2,3-oxa-diazol-3-ylium-5-olate}, C13H12N2O5, the aromatic substitutent is 2-(eth-oxy-carbon-yl)phenyl. Intra- and inter-molecular hydrogen bonds are observed. The ...
متن کاملName: Avafia Dossa Title: Routes to Functionalized ortho-Alkynyl and Fused-Ring Sydnones
In this work, suitably functionalized arylsydnones were used to synthesize ortho-alkynyl sydnones as precursors to functionalized sydnoquinolines. The versatile intermediates, 3-(4-halo-2-iodophenyl)sydnones and 3-(3-halo-2-iodophenyl)sydnones have been synthesized in moderate to good yield using a sequence involving dilithiation of 3-(4-halophenyl)-sydnones and 3-(3-halophenyl)sydnones using t...
