(Diacetoxyiodo)benzene-Mediated Reaction of Ethynylcarbinols: Entry to α,α'-Diacetoxy Ketones and Glycerol Derivatives.

ABSTRACT

Efficient access to α,α'-diacetoxy ketones has been developed from ethynylcarbinols and PhI(OAc)2. A plausible mechanism for this was proposed on the basis of experimental studies. The usefulness of α,α'-diacetoxy ketone products has been documented, and glycerol derivatives can be easily synthesized in good yields via a one-pot reaction.
