Abstract

[reaction: see text] Quinovic acid glycosides were microbially deglycosylated by a Nocardia sp. to their aglycon quinovic acid and its biogenetic counterpart, cincholic acid (3), via an unprecedented carbon skeleton rearrangement involving a methyl group migration. The structures of the metabolites were established by ESI-LC/MS and 2D-NMR techniques.
