Discovery of hypoiodite-mediated aminyl radical cyclization lacking a nitrogen radical-stabilizing group: Application to synthesis of an oxazaspiroketal-containing cephalostatin analog

Synthesis of an oxazaspiroketal-containing bissteroidal pyrazine is described. The key transformation of this synthesis involves stereoselective formation of oxazaspiroketal via aminyl-radical cyclization of primary amine lacking a radical-stabilizing gro
