The palladium-catalyzed reaction of arenediazonium tetrafluoroborates with methyl 4-hydroxy-2-butenoate in MeOH under mild conditions gives 4-arylbutenolides usually in good to high yields through a domino vinylic substitution/cyclization process. The rea

Bistributylstannyl-2(5H)-furanone 4a has been prepared from 3-(tetrahydropyran-2-yl)oxy but-2-ynoate and shown to exhibit good selectivity in its Stille reactions with a range of halogenated compounds, leading to 4-substituted-3-stannyl-2(5H)-furanones, in generally moderate yield. Under certain reaction conditions, doubly substituted products were also isolated from the reactions. The 3,4-bistrimethylstannyl furanone, 4b, corresponding to 4a was prepared, but decomposed during all attempts to execute Stille reactions upon it.

3- and 4-trialkylstannylfuranones (2) and (3) have been prepared by an interesting desulphurative stannylation reaction; 3- and 4-substituted 2-(5H)-Furanones (12) and (13) may be prepared via palladium-catalysed cross coupling of (2) and (3) with aryl iodides.
