Acid-catalyzed rearrangement of cyclobutanols. A novel rearrangement

The acid-catalysed dehydration-rearrangement reaction of α-thienyl cyclobutanols 3 and 4 resulted in the formation of tetrahydronaphthothiophenes 5a and 6a.The rearrangement to the linearly fused PAH system instead of the expected angularly fused system reflects α-scission of the cyclobutyl ring.A mechanism based on deuterium labelling studies is propesed to account for the product formation.
