Indium-promoted allylation reaction of imino-isatins in aqueous media: Synthesis of quaternary 3-aminooxindoles

Alcaide, Benito,Almendros, Pedro,Aragoncillo, Cristina

, p. 2845 - 2848 (2010)

Quaternary 3-amino-2-oxindoles have been obtained via allylation and propargylation reactions of imino-isatins in aqueous media promoted by In and Zn respectively, under Barbier conditions, in good to excellent yields. A quaternary new stereocenter has been formed without hydrolysis of the starting imino-isatin
