  A New Construct of the cis-3a-Aryloctahydroindole Skeleton via the [4+2] Cycloaddition of Furanyl Carbamates

  摘要：

  2-methylthio-5-amidofurans containing tethered unsaturation were prepared via the reaction of dimethyl(methylthio)sulfonium tetrafluoroborate (DMTSF) with beta-alkoxy-gamma-dithiane amides. Thermolysis of these furans resulted in an intramolecular Diels-Alder reaction (IMDAF). The resulting oxa-bridged cycloadducts underwent a subsequent rearrangement to form bicyclic lactams. Model studies were directed toward mesembrine as well as the core skeleton of the 3,4-benzoerythrinane skeleton. Using this cascade sequence, a formal synthesis of the alkaloid erysotrine was accomplished.
