title: First total synthesis of (+/-)-3-aza-11-oxa-1,3,5(10)-trieno steroids.
abstract: We set out to describe a new and versatile method for preparing 3-aza-11-oxa-1,3,5(10)-trieno steroids via an intramolecular Diels-Alder cycloaddition of o-quinodimethanes as the key step. The characteristic 1H and 13C NMR spectroscopic features of the synthesized compounds are reported.
