General description

4-Formyl-1-methylpyridinium benzenesulfonate is a pyridinium salt widely used for the conversion of primary amines to the carbonyl compounds like aldehydes and ketones. The reaction conditions are mild, suitable for compounds with sensitive functional groups thereby providing an efficient alternative for such transformations.

Application

4-Formyl-1-methylpyridinium benzenesulfonate may be used as a reagent in the synthesis of the following:
  • tetrazolic analogs of chalcones
  • (+)-ferruginol
  • Ecteinascidin 743
  • Galipea alkaloids
