An Oxidopyrylium Cyclization/Ring-Opening Route to Polysubstituted α-Hydroxytropolones
摘要:
alpha-Hydroxytropolones are a class of molecules with therapeutic potential against several human diseases. However, structure-activity relationship studies on these molecules have been limited due to a scarcity of efficient synthetic methods to access them. It is demonstrated herein that alpha-hydroxytropolones can be generated through a BCl3-mediated ring-opening/aromatization/demethylation process on 8-oxabicyclo[3.2.1]octenes. Used in conjunction with an improved method based on established oxidopyrylium dipolar cycloadditions, several polysubstituted alpha-hydroxytropolones can be accessed in three steps from readily available alpha-hydroxy-gamma-pyrones.
