title = "A Stereocontrolled Annulation of the Taccalonolide Epoxy Lactone onto the Molecular Framework of trans-Androsterone",
abstract = "A robust and scalable route to the taccalonolide skeleton starting from trans-androsterone is presented. The synthesis features a cyclic hydroboration carbonylation reaction, which effectively establishes the trans-hydrindane DE ring junction in a remarkable annulation reaction, as well as a Claisen rearrangement and a catalytic Ullmann-type cyclization. This work is part of a larger effort to uncover new clinical candidates from the taccalonolide class of anticancer agents through advances in chemical synthesis.",
