In this paper we describe the peculiar properties of a polycyclic compound (2), derived from a Diels–Alder adduct, which undergoes spontaneous cyclization to 3 when kept in chloroform solution. Stable intermediates needed for our studies on the synthesis of heliangolides were obtained only after reduction of the double bonds of 2.
