资源简介：
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.
