An undergraduate organic chemistry experiment based on literature reports in which the aldehyde functionality of citronellal is reduced to the primary alcohol is reported. The reducing agent, poly(methylhydro)siloxane (PMHS), is activated via a catalytic amount of fluoride. This polymeric reducing ...

The reduction of acyl-CoA or acyl-ACP to fatty alcohol occurs via a fatty aldehyde intermediate. In prokaryotes this reaction is thought to be performed by separate enzymes for each reduction step while in eukaryotes these reactions are performed by a single enzyme without the release of the int...
The reducing reagents were simple primary or secondary alcohols, e.g. 2-propanol. The supported Sn and Zr oxides catalysts were active and selective for the reduction of crotonaldehyde (C4-unsaturated aldehyde: CH3CH=CHCHO) to crotyl alcohol (the corresponding unsaturated alcohol: CH3CH=CHCH2OH)...

The invention concerns a process for the preparation of an alpha -substituted- alpha -cyanomethyl alcohol enantiomer of formula I wherein the group R<1> is an alkenyl, alkynyl, aryl or heteroaryl group by reacting an aldehyde of ... WILLIAM ROY JACKSON,BARRY ROSS MATTHEWS,COLIN WILSHIRE - ...
(COMT) methylates 5-hydroxyconiferaldehyde to produce sinapaldehyde. COMT is a promiscuous enzyme that has the ability to catalyze both 5-O- and 3-O-methylation of several lignin pathway intermediates including acids and alcohols, suggesting a functional redundancy between CCoAOMT and COMT in ...
alcohol oxidation to aldehyde51, CH4oxidation to CH3OH52,53, and CO2reduction to CH4, CH3OH, and HCOOH54. However, the role of H2O in the reduction of CO2to CO is ambiguous. To elucidate the role of H2O in CO2RR, we investigated the behavior of Cu+and [Cu(H2O)]+and found that ...
oxidize a benzylic alcohol to an aldehyde and performs the reverse reaction with the reduced form, NADH25,26,27. This ribozyme possesses the ability to alter the rate of the oxidation and reduction reactions, a kinetic property, but changes to the Emof the cofactor, a thermodynamic property, ...
The reaction mechanism of Clemmensen reduction has not completely been clarified, but it is well known that the alcohol is not an intermediate. As summarized in Scheme 3,8,14 the reduction is thought to occur on the zinc metal surface, and involves protonation of the carbonyl function and a ...
