Abstract: The present invention relates to tri-functional crosslinking reagents carrying (i) a ligand-reactive group for conjugation to a ligand of interest having at least one binding site on a target glycoprotein receptor, (ii) a hydrazone group for the capturing of oxidized receptor-glycoproteins and (iii) an affinity group selected from azides and aklynes for the detection, isolation and purification of captured glycoproteins; as well as their manufacturing. The invention further provides for improved methods of detecting, identifying and characterizing interactions between ligands and their corresponding target glycoproteins on living cells and in biological fluids. The invention further provides for new uses of catalysts in such methods.

Abstract: A process for the preparation of diols by a Lewis acid-catalysed aldehyde addition reaction on hydroxyalkynes followed by hydrogenation is described. The process provides a wide range of diols from simple, readily available starting materials. In particular the process is suitable for preparing chiral 1,4-diols suitable for the preparation of chiral phospholane ligands for use in asymmetric catalysis.
