By utilising an oxazole–alkyne Diels–Alder reaction, 3,4-bis(tributylstannyl)furan is prepared and its synthetic potential assessed by its conversion into several 3,4-disubstituted furans via Stille-type palladium-catalysed reactions.
4-Aryl-3-substituted furans IIIa - IIId were prepared by Diels Alder reaction of 4-phenyloxazole (I) with compounds IIa - IId, containing an activated triple bond, and subsequent thermal decomposition of the cycloadduct.
