The fight against bacterial infection represents one of the continuing challenges in medicine. Orienticin C belongs to the vancomycin family of antibiotics and its complex molecular architecture makes its synthesis a real challenge. Herein the total synthesis of Orienticin C aglycone is described, in which ruthenium-mediated intramolecular etherification is used as a key step for the construction of the biaryl ether linkages.
