High-pressure diels-alder reactions of bicyclic dienones. short syntheses of hydrophenanthrenones
Diels-Alderreactions of a heteroannularbicyclicdienone with acyclic dienes under Lewis acid catalysis at atmospheric and 7 Kbar pressure are presented. The pressure reactions are fast, high-yielding and highly diastereoselective en route to hydrophenanthrenones. As a consequence of some post-cycloaddition enolization. both cis and trans products are available.
