A chemoselective, one-pot transformation of aldehydes to nitriles

This paper describes a procedure for direct conversion of aldehydes to nitriles using O-(diphenylphosphinyl)hydroxylamine (DPPH). Aldehydes are smoothly transformed to their corresponding nitriles by heating with DPPH in toluene. The reaction can be accomplished in the presence of alcohol, ketone, ester, or amine functionality.

Enantioselective organo-singly occupied molecular orbital catalysis: The carbo-oxidation of styrenes

The first enantioselective organocatalytic carbo-oxidation of styrenes has been accomplished using singly occupied molecular orbital (SOMO) catalysis. Geometrically constrained radical cations are generated from the one-electron oxidation of enamines formed from the condensation of aldehydes with a secondary amine catalyst. These SOMO-activated radical cations are susceptible to attack by commercially available styrenes, forming gamma-oxyaldehyde products with uniformly high levels of asymmetric induction. Broad latitude in both the aldehyde and styrene scope is readily tolerated. This report highlights the potential of SOMO catalysis to enable the development of entirely new classes of asymmetric reactions that have no traditional catalytic equivalents. Copyright

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: tert-Butyl 4-(2-oxoethyl)piperidine-1-carboxylate, you can also check out more blogs about142374-19-4

Enantioselective Formal alpha-Methylation and alpha-Benzylation of Aldehydes by Means of Photo-organocatalysis

Detailed herein is the photochemical organocatalytic enantioselective alpha-alkylation of aldehydes with (phenylsulfonyl)alkyl iodides. The chemistry relies on the direct photoexcitation of enamines to trigger the formation of reactive carbon-centered radicals from iodosulfones, while the ground-state chiral enamines provide effective stereochemical control over the radical trapping process. The phenylsulfonyl moiety, acting as a redox auxiliary group, facilitates the generation of radicals. In addition, it can eventually be removed under mild reducing conditions to reveal methyl and benzyl groups.
