Abstract

A highly efficient total synthesis of the 11-membered cyclic aspercyclides A (1) and B (2) has been achieved by chemo- and regioselective intramolecular oxidative C–O bond formation from differently substituted diphenols. ... In 2004, Singh and co-workers isolated and characterized aspercyclides A (1), B (2), and C from the fermentation broth of Aspergillus sp.(1) Aspercyclide A (1) inhibited the binding of immunoglobulin E antibodies (IgE) to the human IgE ...
