Substituent control in the synthesis of tetrahydropyrans, oxepanes and oxocanes by episulphonium ion-mediated cyclisation

Cyclisation of the heptenols (1), (6a), (6b), and (6c) to cyclic ethers via episulphonium ions has been studied and the effect of allylic substituents on the size of ring produced has been explored.
