Intramolecular oxidative cyclisation of 5-stannyl-1,3-pentanediol derivatives with lead tetra-acetate
Abstract
The oxidative cyclisation of 5-stannyl-1,3-pentanediol derivatives gave corresponding 4-hydroxytetrahydropyrans in excellent yields, and its applications to the synthesis of dioxabicyclodecane 12 and 4-hydroxy-δ-lactone 14 are also described.
