, p. 5469 - 5472 (2007/10/02)
An efficient diastereoselective synthesis of 2 is presented. A key feature is the intramolecular Diels-Alder reaction of o-quinodimethanes intermediates 3 derived from benzocyclobutenes 4 in which the exotransition state is favored by incorporation of an amide functionality.
