Pyranose .alpha.-enones provided ready access to functionalized trans-decalins via bis-annulated pyranosides obtained by intramolecular Diels-Alder reactions. A key intermediate for forskolin.
摘要:
Intramolecular Diels-Alder routes for the preparation of bis-annulated pyranosides, as chiral precursors of functionalized trans-decalin rings of terpenoid natural products, have been investigated.
