A reaction between ethyl α-cyanocinnamate and o-phenylenediamine under thermal conditions yielded 2-cyano-3-phenyl-propionic acid ethyl ester, 2-phenyl benzimidazole, and ethyl cyanoacetate. The mechanistic revelations led to the development of a simple and efficient transfer-hydrogenation process from the in situ generated benzimidazolines to activated olefins under solventless and catalyst-free conditions.

Economic and environmentally friendly bio-mimetic one-pot three and four-component Knoevenagel-hydrogenation (K-H), five-component Knoevenagel-hydrogenation-alkylation (K-H-A) and six-component Knoevenagel-hydrogenation-alkylation-Huisgen cycloaddition (K-H-A-HC) reactions of aldehydes, CH-acids, o-phenylenediamine, alkyl halides and azides using proline, proline-metal carbonate and proline-metal carbonate-Cu I-catalysis, respectively have been developed. Many of K-H and K-H-A compounds have direct application in pharmaceutical chemistry. The Royal Society of Chemistry.
A novel and green protocol for two-carbon homologation: A direct amino acid/K2CO3-catalyzed four-component reaction of aldehydes, active methylenes, Hantzsch esters and alkyl halides
Ramachary, Dhevalapally B.,Kishor,Ramakumar
, p. 651 - 656 (2007/10/03)
A novel and green approach for the two-carbon homologation of aldehydes using amino acid catalysis has been developed and further extended to the generation of pharmaceutically active cyano-esters via four-component reactions in one-pot.
Phase-transfer Catalysis: A Convenient Tool for the Functionalization of Benzocyclobutene-1-carbonitrile
Fedorynski, Michal,Zielinski, Marek,Jonczyk, Andrzej
, p. 36 - 37 (2007/10/03)
Benzocyclobutene-1-carbonitrile 1 is further functionalized at the 1-position by reaction with electrophilic compounds in the presence of concentrated aqueous alkali metal hydroxides and tetra-n-butylammonium bromide as a phase-transfer catalyst.
