Abstract
Successful Claisen rearrangement of a number of 1,4‐diaryloxy‐2‐butynes is reported. The products of such a rearrangement are the benzofuro[3,2‐c]benzopyrans. This novel rearrangement offers a facile synthetic route to tetracyclic derivatives resembling the naturally occurring pterocarpans.Keywords
