摘要：

Upon treatment with solely a hypervalent iodine reagent of phenyliodine(III) bis(tri-fluoroacetate) (PIFA), 3-(2-hydroxyphenyl)-3-oxo-N-phenyl propanamides and a series of its derivatives were conveniently converted to a class of undocumented spirofurooxindoles under mild conditions. Control experiments provided evidence that this spirocyclization process encompassed a cascade oxidative reactions involving the formation of a C-O bond prior to that of C-C bond.
