Microwave-assisted synthesis of N-arylglycines: Improvement of sydnone synthesis

Reactions of anilines with ethyl bromoacetate under microwave irradiation have afforded N-arylglycines that are subsequently converted to their N-nitroso derivatives with a combination of silica chloride or periodic acid, wet SiO2 and sodium nitrite in CH2Cl2 with satisfactory yields. In the final step, the use of 1,3-dibromo-5,5-dimethylhydantoin (DBH) as a new and effective reagent for dehydration of N-nitroso-N-arylglycines to sydnones was successfully examined.

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,

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.
