A new synthetic approach to biologically relevant spiro[pyrrolidine-3,3'-oxindoles] was developed on the basis of the cascade transformation of 3-(2-azidoethyl)oxindoles via Staudinger/aza-Wittig/Mannich reactions. The parent azides were readily synthesized through a nucleophilic ring opening of spiro[cyclopropane-1,3'-oxindoles] with the azide ion. A(More)
