Vanadium Complex-catalyzed Enantioselective oxa-Piancatelli Rearrangement Reaction

摘要

4-Hydroxy-2-cyclopentenone derivatives have received a great deal of interest by organic chemists due to a useful building block in the various natural product synthesis. Among preparation methods for 4-hydroxy-2- cyclopentenones reported so far, oxa-Piancatelli reaction, which represents the original Piancatelli reaction first reported in 1976, is one of the most straightforward way to access to the corresponding compounds from readily available furfuryl alcohols.
