Aculeatones A and B, epimeric lovastatin derivatives with a 6/6/3-tricyclic carbon skeleton from Aspergillus aculeatus and their chemical transformation

Abstract

Lovastatin derivatives aculeatones A–F (1–6) with lipid-lowering activity were isolated from Aspergillus aculeatus. 1 and 2 represent the first examples with a 6/6/3-tricyclic scaffold and the biomimetic formation of 1 was achieved starting from 3.
