Synthesis of the 1,6,8-trioxadispiro[4.1.5.2]tetradec-11-ene ring system present in the spirolide family of shellfish toxins and its conversion into a 1,6,8-trioxadispiro[4.1.5.2]-tetradec-9-en-12-ol via base-induced rearrangement of an epoxide

The synthesis of the 1,6,8-trioxadispiro[4.1.5.2]tetradec-11-enes 12 present in the shellfish toxins spirolides B 1 and D 2, is reported. The two spirocentres were constructed via iterative radical oxidative cyclization of hydroxyalkyl dihydropyran 14 and
