The palladium-catalyzed annulation of 1,3-dicarbonyl compounds, such as methyl 3-oxobutanoate or acetylacetone, with methyl prop-2-ynyl carbonate (56) yields alkylidenedihydrofurans 57, which can be converted directly into tri- and tetrasubstituted furans 58 via a [1,3]-H shift by passing them through a short silica-gel column (Scheme 20).[142,143]
