A hydrogen atom transfer (HAT)-initiated Dowd–Beckwith rearrangement reaction was developed, which enables the efficient assembly of diversely functionalized polyquinane frameworks. By incorporation of an iridium-catalyzed regio- and enantioselective hydrogenation and a diastereocontrolled ODI-[5+2] cycloaddition/pinacolrearrangement cascade reaction, the asymmetric total syntheses of eight tetraquinane
