Cortistatins, isolated from Cortisium simplex in 2006, exhibit potent inhibition against the proliferation of human umbilical vein endothelial cells (HUVECs). This paper describes the details of our total synthesis of cortistatins A and J. The key features of our strategy include (1) an efficient Knoevenagel/electrocyclic reactions to couple the diketone and the CD-ring fragment, (2) a chemoselective radical cyclization to construct the oxabicyclo[3.2.1]octane system, (3) a highly stereocontrolled installation of the isoquinoline unit, and (4) a late-stage functionalization of the A-ring.
