Abstract

(Chemical Equation Presented) The scope and limitations of a regioselective synthesis of either α- or β-substituted γ-hydroxybutenolides from 3-furfural and enones are described. The sequence features a Baylis-Hillman reaction followed by singlet oxygen oxidation with use of either an amine base or TBAF as the regioselectivity switches. Structural studies in solution on some of the resulting γ-hydroxybutenolides are also reported.
