  A Unified Strategy for the Synthesis of Phenanthroizidine Alkaloids:  Preparation of Sterically Congested Pyridines

  摘要：

  Total syntheses of the representative phenanthroizidine alkaloids, tylophorine and antofine, and of their seco congeners, septicine and julandine, have been completed from sterically congested 3,4-diarylpyridines prepared by a modified Knoevenagel-Stobbe synthesis. Central to the success of this effort was the ability of alpha-dicarbonyl enones to combine in a formal [4 + 2]-cycloaddition with sterically demanding vinyl ethers.
