Alkaloid inspired spirocyclic oxindoles from 1,3-dipolar cycloaddition of pyridinium ylidesTools Day, Jonathan, Uroos, Maliha, Castledine, Richard A., Lewis, William, McKeever-Abbas, Ben and Dowden, James (2013) Alkaloid inspired spirocyclic oxindoles from 1,3-dipolar cycloaddition of pyridinium ylides. Organic and Biomolecular Chemistry, 11 (38). pp. 6502-6509. ISSN 1477-0520 Full text not available from this repository.AbstractCycloaddition reactions between pyridinium ylides and 3-alkenyl oxindoles that proceed in high yield and with very good regio- and diastereoselectivity are reported. The resulting cycloadducts have the same stereochemistry of biologically active oxindole alkaloids, such as strychnofoline.
