Three-component reactions of monoalkyl malonates, cyanoacetic acids or 2-ketocarboxylic acids, N-methylglycine, and formaldehyde were developed to rapidly access 3-substituted pyrrolidines in 17–97% yield. These reactions represent a double decarboxylative domino-sequence promoted by pyrrolidine and involve N-methylazomethine ylide as the reactive intermediate.

Hayashi, Chika,Hayashi, Takuo,Yamada, Tohru
, p. 862 - 870 (2015/06/25)
The gaseous carbon dioxide incorporation reaction with α,β-unsaturated compounds was examined in the presence of a catalytic amount of bis(acetylacetonato)cobalt(II) and using diethylzinc as a reductant. After screening with various electron-withdrawing g

[Chemical Equation Presented] Palladium-catalyzed decarboxylative α-allylation of nitriles readily occurs with use of Pd2(dba) 3 and rac-BINAP. This catalyst mixture also allows the highly regiospecific α-allylation of nitriles in the presence of much more acidic α-protons. Thus, the reported method provides access to compounds that are not readily available via base-mediated allylation chemistries. Lastly, mechanistic investigations indicate that there is a competition between C- and N-allylation of an intermediate nitrile-stabilized anion and that N-allylation is followed by a rapid [3,3]-sigmatropic rearrangement.
Electrochemical reduction of cinnamonitrile in the presence of carbon dioxide: Synthesis of cyano- and phenyl-substituted propionic acids

Basu, Manas K.,Sarkar, Dipak C.,Ranu, Brindaban C.
, p. 627 - 632 (2007/10/02)
Carboxylic esters, when refluxed in an aqueous suspension of Dowex-50, furnish the corresponding carboxylic acids in excellent yields.Tertiary esters and nitriles remain unaffected under this condition and β-keto esters undergo smooth decarboxylation.
