An efficient three-step synthesis for benzotropolones via three catalytic steps is presented. Pyrogallol phenones are formed in the first step starting from pyrogallol, which is acylated by proton-catalysis. Catalytic hydrogenation of the phenones yi

Lyophilized cells of the open accessible bacterium Comamonas testosteroni DSM 1455 proved to be an excellent catalyst for the asymmetric reduction of different α-azido, α-bromo, and α-nitro ketones at elevated substrate concentrations (16 g/L) in

Fucosyl transferase III (FucT III) has previously been characterized as the most general enzyme of the FucT family, as judged from its ability to catalyze the transfer of fucose to both Galβ(1-3)GlcNAc and Galβ(1-4)GlcNAc. In order to explore the s

Glycopolymers are useful macromolecules with a non-carbohydrate backbone for presenting saccharides in a multivalent form. Here, a new methodology is described which allows easy access to water-soluble, biodegradable glycopolymers with both predeterm

A series of methyl hexopyranosiduronic acids are coupled to type I disaccharide amines to give ‘trisaccharides’ which have the natural N -acetyl group of the type I disaccharides replaced by uronic acids (→ saccharopeptides). These saccharopept

A series of glycohexopyranuronic acids are coupled to glucosamines to give 'disaccharides' which have the natural N-acetyl group of the glcNAc-moiety replaced by various sugar acids (-->saccharopeptides). These saccharopeptides are surprisingly good
