New versatile approach to alpha-hydrazonoesters and amino acid derivatives through a modified Japp-Klingemann reaction
Addition of diazonium tetrafluoroborates to an acyl chloride pyridine mixture affords hydrazonoacid derivatives in smooth conditions; this new Japp-Klingemann reaction emphasizes the synthetic potential of electrophilic addition to ketenes.
