  β-Vinyl-γ-butyrolactones via the palladium-catalysed reaction of vinyl triflates with Z-2-buten-1,4-diol

  摘要：

  The palladium-catalysed reaction of vinyl triflates with Z-2-buten-1,4-diol affords beta-vinyl-gamma-butyrolactols (4-vinyl-2-hydroxy-tetrahydrofurans) which are converted into the corresponding beta-vinyl-gamma-butyrolactones by a smooth oxidation with Ag2CO3 on celite. Preparation of beta-substituted-gamma-butyrolactones can be performed without the isolation of the intermediate gamma-butyrolactols, thus simplifying the procedure and usually with higher overall yields. The outcome of the palladium-catalysed formation of beta-substituted-gamma-butyrolactols strongly depends on the nature of the added base. Best results are obtained by using NaHCO3 or K2CO3 in the presence of n-Bu4NCl or TEBA.
