Total synthesis of the novel angiogenesis inhibitors epoxyquinols A and B

Abstract

The synthesis of the recently discovered angiogenesis inhibitors epoxyquinols A and B, having novel polyketide derived dimeric structures, has been accomplished from the readily available Diels-Alder adduct of cyclopentadiene and p-benzoquinone through a short, simple and flexible strategy that is diversity oriented and can be adapted to an asymmetric variant.
