ChemInform Abstract: X=Y‐ZH Systems as Potential 1,3‐Dipoles. Part 9. Azaallyl Anion Precursors from the Reaction of (1,3‐Dioxoindan‐2‐ylidene)malononitrile with α‐Amino Acids and Their Methyl Esters.

Abstract The reactions between the malononitrile (I) and glycine (IIa), valine (IIb) or the amino acid esters (IIc)‐(IIe) proceed via a Michael addition/elimination sequence and regiospecific substitution of one of the cyano groups to afford the products (III).
