Abstract
Ytterbium(III) triflate-catalyzed ring opening of substituted 1-cyclopropyl-2-propyn-1-ols with sulfonamides as an efficient synthetic route to conjugated enynes is described herein. The reaction was operationally straightforward and accomplished in moderate to good yields and regioselective manner in all except one case under mild conditions.
