	abstract = {This work describes a rapid and high yielding oxidation of 14 tryptophanylated amino acid methyl esters to the corresponding 3 alpha-hydroxypyrrolo[2,3-b]indoline (Hpi) amino acids with generally facile separation of syn-cis and anti-cis diastereomers. Structural X-ray diffraction data are presented for both diastereomers of Tr-Hpi-Gly-OMe, which allow for a putative assignment of the other 13 pairs of diastereomers reported herein, based on correlations with H-1 NMR chemical shifts. Selective and high yielding deprotection at either the N or C terminus is described, allowing the Hpi motif to be introduced efficiently into potential targets with minimal protecting group manipulation. Two tripeptides containing Hpi and cysteine were prepared and treated with acid in the Savige-Fontana reaction to produce a cyclic tryptathionine linkage, characteristic of both amatoxins and phallotoxins.},

Partial hydrogenation of the aromatic rings in lignin was confirmed by H-1 NMR spectroscopy. The ability of the catalyst to hydrogenate the lignin model compound 2-methoxy-4-propylphenol is critically dependent on the reaction medium: hydrogenation proceeds faster in aqueous ethanol than in aqueous dioxane, aqueous methyl cellosolve or anhydrous ethanol while no hydrogenation occurs in aqueous DMF.},
