Total Synthesis and Stereochemical Assignment of Talaroconvolutin A and Talarofuranone: Gram‐scale Synthesis of Ferroptosis Inducer Talaroconvolutin A

Abstract

Comprehensive SummaryThe first total synthesis of talaroconvolutin A (1.1 g obtained) and talarofuranone has been achieved using accessible materials (12 steps, 7.5% and 8.2% yields, respectively). Convergent routes involved intramolecular Diels−Alder reactions in two approaches for creating the decalin moiety. Additionally, an unprecedented DMP‐mediated domino reaction resulted in the deoxy‐tetramic acid system. These syntheses not only establish the absolute configuration of talaroconvolutin A but also enable further collaborative studies of this type of ferroptosis inducers.
