TL;DR: In this paper, the IMDA diastereoselectivity of benzocyclobutenes such as 2 was compared to 19-nor steroids and in order to compare the diastreoselectivities observed for the intramolecular Diels-Alder reactions of o -quinodimethanes generated either from 1 or 2, the thermolysis of benzoclobunitene 2 was reexamined.

TL;DR: The IMDA diastereoselections reported herein were highly dependent on the nature of the hydroxyl protective group and the diasterenoselectivities superior to those observed with the thermolysis of the corresponding benzocyclobutenes.
