Dramatic solvent effect on the diastereoselectivity of Michael addition: Study toward the synthesis of the ABC ring system of hexacyclinic acid

During our studies toward the synthesis of the ABC ring system of hexacyclinic acid, we have observed a dramatic influence of the solvent on both our key steps. The diastereoselectivity of the intermolecular Michael addition could be totally reversed by c
