A visible light driven catalytic cycle for hydrocarboxylation of alkenes with CO2 was established using a combination of a Rh(i) complex as a carboxylation catalyst and [Ru(bpy)3]2+ (bpy = 2,2′- bipyridyl) as a photoredox catalyst. Two key steps, the generation of Rh(i) hydride species and nucleophilic addition of π-benzyl Rh(i) species to CO2, were found to be mediated by light.
Palladium-Catalyzed Direct Arylation of C(sp3)-H Bonds of α-Cyano Aliphatic Amides
Reddy, M. Damoder,Watkins, E. Blake
, p. 11447 - 11459 (2015/12/05)
Pd(OAc)2-catalyzed arylation of C(sp3)-H bonds in α-cyano-α-methyl aliphatic amides is achieved in the presence of 8-aminoquinoline, as a removable directing group, using Mn(OAc)2 and Na2CO3. The current strategy enables the placement of an aryl/heteroaryl group at the β-position of α-cyano aliphatic acids for the first time. Wide functional group tolerance and easily accessible starting materials provide an efficient protocol for the synthesis of arylated α-cyano amides. Furthermore, the synthetic utility of the products has been demonstrated by their efficient conversions to medicinally important α,α-dialkylated acid and β-amino acid derivatives.

Nitrilase-catalyzed selective hydrolysis of dinitriles and green access to the cyanocarboxylic acids of pharmaceutical importance

, p. 1667 - 1670 (2008/02/11)
To further explore its synthetic applications, the nitrilase bll6402 from Bradyrhizobium japonicum strain USDA110 has been examined toward the hydrolysis of various dinitriles. It has been found that nitrilase bll6402 effectively hydrolyzed α,ω-dinitriles to ω-cyanocarboxylic acids, and the selectivity was independent of the substrate chain length. This feature is distinct from all the known nitrilases of various sources. Nitrilase bll6402 was thus applied to the synthesis of 1-cyanocycloalkaneacetic acids, the useful precursors for the synthesis of gabapentin and its analogues.
Exploring the synthetic applicability of a cyanobacterium nitrilase as catalyst for nitrile hydrolysis
Mukherjee, Chandrani,Zhu, Dunming,Biehl, Edward R.,Hua, Ling
, p. 5238 - 5242 (2007/10/03)
The substrate specificity and synthetic applicability of the nitrilase from cyanobacterium Synechocystis sp. strain PCC 6803 have been examined. This nitrilase catalyzed the hydrolysis of both aromatic and aliphatic nitriles to the corresponding acids in high yields. Furthermore, the stereoselective hydrolysis of phenyl-substituted β-hydroxy nitriles to (S)-enriched β-hydroxy carboxylic acids and selective hydrolysis of α,ω- dinitriles with five or less methylene groups to ω-cyano carboxylic acids have been achieved. This suggested that nitrilase from Synechocystis sp. PCC 6803 could be a useful enzyme catalyst for the "green" nitrile hydrolysis. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
