| Abstract
| - Redox isomerization is a synthetically important processbecause it creates two new functional groups in the product,among which is the isomerization of propargylic alcoholsto conjugated enones. Although E-enones have been preparedby this approach, Z-enones could not be accessed. Wepreviously reported DABCO-catalyzed E-selective isomerization of electron-deficient propargylic alcohols to enonesand its mechanism. Based on this mechanism, we have nowdeveloped the first Z-selective redox isomerization ofelectron-deficient propargylic alcohol to enone using sodiumbicarbonate as a catalyst.
