Total synthesis of maoecrystal V: early-stage C-H functionalization and lactone assembly by radical cyclization.

ABSTRACT: A total synthesis of the unusual ent-kaurane maoecrystal V is described. The synthesis strategy features a counterintuitive early disconnection of the lactone subunit to a polycyclic enol ether intermediate in order to preserve the central tetrahydrofuran ring until the beginning stages of the synthesis. This strategy enables an application of C-H functionalization at the early phase of the synthesis during the construction of a dihydrobenzofuran intermediate.
