Convenient synthesis of 3-Hydroxyquinolines via dakin oxidation: A short synthesis of Jineol

[Display omitted] •Simple methodology for the synthesis of 3-hydroxy quinolines.•Unprecedented Dakin oxidation of quinoline-3-carboxaldehydes.•Substituted quinoline-3-carboxaldehydes are more suitable for Dakin oxidation.•Efficient total synthesis of quinoline alkaloid Jineol via Dakin oxidation. A convenient synthesis of 3-hydroxyquinolines has been described via unprecedented Dakin oxidation of quinoline-3-carboxaldehydes. Subsequently, application of the methodology to a high yielding synthesis of quinoline alkaloid Jineol (1) is reported.
