A Convergent Total Synthesis of 19‐Hydroxysarmentogenin

19 in 19: A convergent total synthesis of 19-hydroxysarmentogenin has been achieved, starting from three simple fragments. The desired product was synthesized in 19 steps from the AB ring system with the installation of six stereocenters and the formation of three CC bonds.
