Stereocontrolled Total Syntheses of (±)-Fawcettimine, (±)-Lycoflexine, and (±)-Lycoflexine <i>N</i>-Oxide

Abstract

New stereocontrolled total syntheses of (±)-fawcettimine, (±)-lycoflexine, and (±)-lycoflexine N-oxide have been accomplished. The highlights include a one-pot annulation to construct the enedione and a microwave-promoted Diels-Alder reaction.
