✦ Synopsis
Exo-trigonal-type intramolecular ring closure of the cf,8-epoxy sulfoxides with hvdroxvl group cave 2-acvl cyclic ethers (5. 6. and 13 membered rings) in good-yields.-
In contrast to this, endo-trigonalltype ring closure of the a,8-epoxy sulfoxides was rather difficult.
Recently, cyclic ethers have received much attention regarding synthetic organic chemistry.
They are found in many natural products having remarkable
