Improved stereochemical analysis of conformationally flexible diamines by binding to a bisporphyrin molecular clip

The relative stereochemistry of acyclic diamines with several stereogenic centers has been analyzed by NMR spectroscopy in combination with conformational deconvolution. Binding to a bisporphyrin molecular clip improves the stereochemical assignment signi

Synthesis of L-arabinitol and xylitol monomers for the preparation of polyamides. Preparation of an L-arabinitol-based polyamide

Dihydrochlorides of 1,5-diamino-1,5-dideoxy-2,3,4-tri-O-methyl-L-arabinitol (and xylitol) and pentachlorophenyl esters of 2,3,4-tri-O-methyl-L-arabinaric (and xylaric) acids have been prepared as suitable bifunctional monomers for linear polycondensations

Helianthoside from Heliaster helianthus, an asterosaponin with a C3'-sulphated pyranose

A new asterosaponin, named helianthoside (1), has been isolated from the butanolic extract of the starfish Heliaster helianthus and its structure established on the basis of extensive spectroscopic experiments and chemical correlations. Helianthoside is the first asterosaponin with a C3'-sulphated xylopyranose. The absolute stereochemistry at C24 was determined by the Trost-Mosher method.

Modified Curtius rearrangements in the selective cleavage of β-D-glucosiduronic acid and β-D-glucosiduronamide linkages

The selective cleavage of β-D-glucosiduronic acid linkages in permethylated carbohydrates is achieved by modified Curtius rearrangements involving (a) reaction of glycosiduronic acids with diphenylphosphoroazidate or (b)treatment of glycosiduronamides wit
