Abstract
Two routes were examined that permit conversion of 4-vinyl-2-azetidinones 7 via intramolecular nitrile oxide-olefin or azide-olefin cycloaddition into tricyclic β-lactams. Stereoselectivity in these cycloadditions as well as further chemoselective transformation of the products were shown to be dependent on the size of the newly formed ring.
