Article abstract of DOI:10.1016/S0040-4039(00)78707-7

γ-Hydroxybutenolides were obtained from the reaction of substituted 2,5-bis(trimethylsiloxy)furans with aldehydes and ketones using titanium tetrachloride activation.Similarly, α,β-unsaturated carbonyl compounds reacted as a Michael receptor with the title compounds to give γ-hydroxybutenolides.
