چکیده
IN THE TITLE SYDNONE COMPOUND [SYSTEMATIC NAME: 3-(4-meth-oxy-phen-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(9)H(8)N(2)O(3), the essentially planar oxadiazole ring [maximum deviation = 0.005 (1) Å] is inclined at a dihedral angle of 30.32 (8)° with respect to the benzene ring. In the crystal, adjacent mol-ecules are inter-connected by inter-molecular C-H⋯O hydrogen bonds into sheets lying parallel to (100). Weak inter-molecular π-π inter-actions [centroid-centroid distance = 3.5812 (8) Å] further stabilize the crystal packing.

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...
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...
متن کاملMesoionic sydnone derivatives: An overview
Mesoionic compounds are dipolar five or six membered heterocyclic compounds in which both the negative and the positive charge are delocalized, for which a totally covalent structure cannot be written, and which cannot be represented satisfactorily by any one polar structure. The most important member of the mesoionic category of compounds is the sydnone ring system. Sydnones are mesoionic comp...
