DEBROMINATION OF 4-BROMO-3-ARYLSYDNONES WITH SODIUM SULFITE

4-Bromo-3-arylsydnones 1 are debrominated to the corresponding 3-arylsydnones 2 in good to excellent yield using sodium sulfite in methanol/water.In contrast to previously employed reagents, the reaction is successful in the presence of electron-donating,

The Efficient Synthesis of 3-Arylsydnones Under Neutral Conditions

Various substituted aryl sydnones can be prepared in high yield under mild, neutral conditions by nitrosation of the appropriate aryl glycine with isoamyl nitrite in dimethoxyethane followed by cyclization with trifluoroacetic anhydride.

Synthesis and Reactions of Sydnone Oximes

Oximino sydnones 1a,b have been prepared and subjected to reaction with a variety of electrophilic reagents.The aldoxime reacted with all of the latter (except acetic anhydride) to give 3-(2-cyanophenyl)sydnone 1h.With acetic anhydride, both sydnone oximes formed the corresponding O-acetates 1i,m.Similarly, O-sulfonates 1l,k,j, respectively, were obtained by reaction of the ketoxime with benzene-, methane- and para-toluenesulfonyl chloride.Thermolysis (on silica) of the O-sulfonates and the O-acetates has been examined.

DEBROMINATION OF 4-BROMO-3-ARYLSYDNONES WITH SODIUM DITHIONITE.

A variety of 4-bromo-3-arylsydnones can be debrominated with sodium dithionite in excellent yield under very mild conditions.

Debromination of 3-Aryl-4-bromosydnones with Sodium Borohydride

Debromination of 4-bromo-3-(2-substituted aryl) sydnones 1 with sodium borohydride in methanol occurs readily to give good yields of the corresponding parent sydnones 2, except in those cases where the aryl substituent also reacts.The utility of the proce
