Abstract A cationic RhI/H8-binap complex catalyzed regio-, diastereo-, and enantioselective [2 + 2 + 2] cycloaddn. of 1,6-enynes with electron-deficient ketones to form fused dihydropyrans contg. two quaternary carbon centers, e.g., I, is reported. Electron-rich aryl ketones react with 1,6-enynes in the presence of the same catalyst to give ortho-functionalized aryl ketones with excellent regio- and enantioselectivity. [on SciFinder(R)]
