The asym. total syntheses of (+)-5-epi-schisansphenin B and the proposed structure of (+)-15-hydroxyacora-4(14),8-diene have been accomplished from 1,3-cyclopentadione in eight synthetic steps. The enantioselective palladium-catalyzed redox-relay Heck alkenylation, the intramol. Stetter reaction, and the regioselective Tiffeneau-Demjanov-type ring expansion were the pivotal steps in these syntheses.
Journal of Organic Chemistry published new progress about Alkenylation, stereoselective (redox-relay Heck). 1416819-91-4 belongs to class pyridine-derivatives, and the molecular formula is C13H15F3N2O, Reference of 1416819-91-4.
