The described semi-synthetic route differs from the previously published approaches by an original C-7–C-8 disconnection. The kinetic enol triflate of Grundmann ketone was chosen as the CD-ring platform on which to couple an A-ring synthon via a challenging sp2–sp3 cross-coupling. A range of A-ring synthons was synthesized to allow the investigations of various conditions of metal-catalyzed couplings
