Asymmetric Total Synthesis of the Complex Polycyclic Xanthone FD‐594
A highly convergent approach was developed to achieve the first asymmetric and scalable total synthesis of FD‐594, a complex polycyclic xanthone natural product from Streptomyces sp. TA‐0256, in a longest linear sequence (LLS) of 20 steps. The trans‐9,10‐dihydrophenanthrene‐9,10‐diol fragment (B‐C‐D...

description | A highly convergent approach was developed to achieve the first asymmetric and scalable total synthesis of FD‐594, a complex polycyclic xanthone natural product from Streptomyces sp. TA‐0256, in a longest linear sequence (LLS) of 20 steps. The trans‐9,10‐dihydrophenanthrene‐9,10‐diol fragment (B‐C‐D ring) was generated through a new strategy involving asymmetric dihydroxylation followed by Cu‐mediated oxidative cyclization. Late‐stage stereoselective glycosylation assembled the angular hexacyclic framework with a β‐linked 2,6‐dideoxy trisaccharide fragment.
Die asymmetrische Totalsynthese des polycyclischen Xanthons FD‐594 gelang durch einen konvergenten und skalierbaren Ansatz. Das trans‐9,10‐Dihydrophenanthren‐9,10‐diol‐Fragment (B‐C‐D‐Ring) wurde durch eine asymmetrische Dihydroxylierung, gefolgt von einer Cu‐vermittelten oxidativen Cyclisierung, erzeugt. Bei der späten stereoselektiven Glykosylierung wurde das hexacyclische Gerüst mit einem β‐verknüpften 2,6‐Dideoxy‐Trisaccharidfragment zusammengesetzt. |
