using phosphinomethyloxazolines as ligands. Asymmetrichydrogenation of analogous cyclopentene derivatives, prepared by Suzuki–Miyaura cross‐coupling, proved to be more difficult and proceeded with lower enantioselectivities of up to 88 % ee. The synthetic potential of this cross‐coupling/asymmetric‐hydrogenation strategy was demonstrated by an enantioselective route to chiral hexahydrofluorenones.
