Estrogen receptor ERα and ERβ heterodimerization has been implicated in cancer chemoprevention. The discovery, structural elucidation, and total synthesis of a new natural product, actinopolymorphol A (1), from Actinopolymorpha rutilus (YIM45725) that preferentially induces ERα/β heterodimerization is reported. Total synthesis of 1 has allowed us to determine its absolute stereochemistry and that of a previously known deacetylated congener, and 1 represents the first member of a new class of natural products not previously recognized to modulate ER function.
