alkylsulfonyl of 1 to 4 carbon atoms or arylsulfonyl, can also be obtained by condensing an aldehyde of the formula ##STR14## wherein R3is as defined above, with a 2-chloromethylbenzimidazolium salt of the formula ##STR15## wherein R1', R2' and R6have the above meanings and X♁ ...
Plant aminoaldehyde dehydrogenases (AMADHs, EC 1.2.1.19) belong to the family 10 of aldehyde dehydrogenases and participate in the metabolism of compounds related to amino acids such as polyamines or osmoprotectants. Their broad specificity covers ω-aminoaldehydes, aliphatic and aromatic aldehydes as...
3). The sequential action of peroxisomal enzymes phytanoyl-CoA hydroxylase and 2-hydroxyacyl-CoA lyase release the carboxyl carbon as formyl-CoA and produce a branched-chain aldehyde, pristanal. Pristanal is then oxidized to pristanic acid (2,6,10,14-tetramethyl pentadecanoic acid), which can ...

The direct regioselective allylation of insitu generated aldehyde acyl anions has been achieved by synergistic NHC and Pd catalysis. It provides an efficient access to valuable β,γ-unsaturated ketones under mild reaction conditions starting from easily accessible allylic carbonates and aldehydes without ...
Acyl radical has assumed an eminent position in the synthetic chemistry due to its unique and often highly reactivity. Using aldehyde as acyl radical source does not require the prefunctionalization of substrate. Furthermore, the formation of acyl radical can be achieved through a hydrogen atom tran...
