Stereoselective synthesis of a novel pseudopeptide hapten for the generation of hydrolytic catalytic antibodies

The synthesis of a novel hapten containing a 1,4-diamino-2,3-diolbutane core unit is described. The molecule contains four stereogenic centres and has been synthesised via a stereoselective route. The absolute stereochemistry of each stereogenic carbon atom has been assigned by nuclear Overhauser effect experiments carried out on a number of derivatives. (C) 2004 Elsevier Ltd.
