  A Stereoconvergent Intramolecular Diels–Alder Cycloaddition Related to the Construction of the Decalin Core of neo-Clerodane Diterpenoids

  摘要：

  Several examples of a highly specific, stereoconvergent intramolecular Diels-Alder cycloaddition that led to the trans-decalin core of neo-clerodane diterpenoids are described. The relative configuration adjacent to the dienophile, which led to C4 of the decalin system, as well as the electron withdrawing effects of various substituents and conformational rigidity of the Diels-Alder precursors were explored.
