3-Aroyl and 3-heteroaroyl substituted 3-oxoalkanenitriles were synthesized by the reactions of activated aromatic and hetero-aromatic substances with cyanoacetic acid in the presence of acetic anhydride. As part of studies focusing on the preparation of cyanoacetyl-1-N-methylbenzimidazole, we observed that reaction of

The bifunctional thiourea-tertiary amine derivatives of simple chiral diamines serve as highly enantioselective catalysts for the Michael addition of alpha-substituted cyanoacetates to vinyl sulfones, giving an efficient protocol for the construction of an all-carbon substituted quaternary stereocentre.
Yijun Huang et al.
Molecular diversity, 15(1), 3-33 (2010-03-02)
The Gewald reaction of sulfur, cyanoacetic acid derivatives, and oxo-component (G-3CR) yielding highly substituted 2-aminothiophene derivatives has seen diverse applications in combinatorial and medicinal chemistry. Its products are of great use in pharmaceutical industry mainly as small molecular weight inhibitors.

Two synthetic routes to bis-armed-alpha-amino acid derivatives are described. The first route involves alkylation of dibromo derivatives with ethyl isocyanoacetate under phase-transfer catalysis (PTC) conditions. The second route uses a palladium-mediated Suzuki-Miyaura cross-coupling reaction between a DL-4-boronophenylalanine derivative and aromatic
