INTRAMOLECULAR RING CLOSURE OF α,β-EPOXY SULFOXIDES WITH HYDROXYL GROUP: A NOVEL SYNTHESIS OF 2-ACYL CYCLIC ETHERS AND 3-KETO CYCLIC ETHERS

Exo-trigonal-type intramolecular ring closure of the α,β-epoxy sulfoxides with hydroxyl group gave 2-acyl cyclic ethers (5, 6, and 13 membered rings) in good yields.In contrast to this, endo-trigonal-type ring closure of the α,β-epoxy sulfoxides was rather difficult.
