Abstract

An enantioselective organocatalytic oxidative spirocyclization of alkyl 3-oxopentanedioate monoamide derivatives leading to the formation of diverse spirofurooxindoles with high enantioselectivity has been realized via chiral aryliodine-mediated cascade C-O and C-C bond formations. The reaction is postulated to proceed via oxidative C-O bond formation followed by oxidative C-C bond formation, with the latter being the enantioselectivity-determining step.
