Synthesis of 4,4-disubstituted piperidine-2-carbonitriles and piperidine-2,6-dicarbonitriles as precursors for newα-amino acids

Schmaunz, Cornelia E.,Wanner, Klaus T.

, p. 3332 - 3342 (2011/12/01)

An easy and straightforward method for the synthesis of 4,4-disubstituted pipecolic acid and piperidine-2,6-dicarboxylic acid derivatives has been developed, based on the addition of cyanide ions to 4,4-disubstituted 1,4-dihydropyridines, which are easily
