Abstract :
A one-pot route to 3-benzo[b]thiophen-2-yl-acrylates (2) from the corresponding thiophenols (1) is reported. Ester reduction and subsequent hydroxyl esterification deliver psuedo trienoates (II) which undergo an intramolecular Diels–Alder (IMDA) reaction to give two 2-oxa-9-thiacyclopenta[b]fluoren-3-one products (I)—the major Diels–Alder product rearomatizes to 7.
