Stereoselective hydrogenation of lignin degradation model compounds
Hu,James,Rettig,Lee
, p. 1234 - 1239 (1997)
Di-μ-chloro-bis(η4-1,5-hexadiene)dirhodium(I) in a two-phase hexane-aqueous medium catalyzes the diastereoselective H2-hydrogenation of lignin degradation model compounds 4-propylphenol, 2-methoxy-4-propylphenol, and 2,6-dimethoxy-4-propylphenol. The all-cis diastereomer is obtained selectively when the phenolic hydroxy group is protected as a methyl ether or when a model compound possessing two methoxy substituents adjacent to the phenolic hydroxy group is used. The relative stereochemistries of the hydrogenated products are established by X-ray crystal structure analysis and (or) 1H NMR.

Hydroamination of alkylphenols by nitriles
Tarasevich,Zhavrid,Kozlov
, p. 1154 - 1159 (2007/10/03)
N-(Alkyl(alkylcyclohexyl)amines were synthesized by hydroamination of o-, m-, and p-alkyl-phenols with aliphatic nitriles. The stereochemistry of the secondary amines formed is described.
