  Synthese der Pestwurzinhaltsstoffe (+)-Petasin und (+)-Isopetasin

  摘要：

  The first total synthesis of optically active petasine 1 and isopetasine 2 succeeded by applying an annelation reaction, based on the reaction of cyclic delta-ketocarboxylic acids with N-phenyliminoketenylidenetriphenylphosphorane. 1 and 2 are biologically active constituents of Petasitis hybridus and were used as antiinflammatory and spasmolytic already in the classical antiquity.
