Guignardones A–C: Three Meroterpenes from <i>Guignardia mangiferae</i>

Abstract

Abstract Guignardones A ( 1 ), B ( 2 ), and C ( 3 ), which are three meroterpenes with frameworks most probably generated through a terpenoid shikimate pathway, were characterized by a combination of spectroscopic, X‐ray crystallographic, and computational methods. The compounds were obtained from cultures of Guignardia mangiferae IFB‐GLP‐4 associated with normal Ilex cornuta leaves.
