A novel strategy for the synthesis of cis‐decalins by an ytterbium‐catalyzed asymmetric inverse‐electron‐demand Diels–Alderreaction of 2‐pyrones and silyl cyclohexadienol ethers is reported here. A broad range of synthetically important cis‐decalin derivatives with multiple contiguous stereogenic centers and functionalities are obtained in good yields and stereoselectivities. A full set of diastereomeric

Re2(CO)10 or Yb(OTf)3 afforded 2H-pyran-2-one derivatives or α,β-unsaturated ketones in moderate to good yields through a highly regioselectivecarbon–carbonbondcleavage pathway. The substituents at the cyclopropane mainly determine the regioselectivity of the carbon–carbonbondcleavage, providing different products of tandem ring-opening and rearrangement reactions.

An enantioselective chemical synthesis of arene cis-dihydrodiols has been realized from 2-pyrones through sequential ytterbium-catalyzed asymmetric inverse-electron-demand Diels-Alder (IEDDA) reaction of 2-pyrones and retro-Diels-Alder extrusion of CO2 . By using this strategy, a series of substituted arene cis-dihydrodiols can be obtained efficiently with high enantioselectivity (>99 % ee in many
