The synthetic antithrombotic argatroban is a dipeptide between the nonproteogenic (2R,4R)-4-methyl-2-piperidine carboxylic acid and l-arginine, in turn bonded to a methyltetrahydroquinoline sulfonyl group. An extensive screening of transition metal-based complexes with different ligands was performed in order to identify the best catalyst for the diastereoselective hydrogenation of a suitable 4,5-dehydropiperidine precursor aimed toward a synthesis of the (2R,4R)-4-methyl piperidine moiety.

, (2008/06/13)
Antibodies to a therapeutic agent and its derivatives and conjugates are disclosed, including antibodies to argatroban and its derivatives and conjugates. The antibodies are useful as reagents in assays and diagnostic kits for determining the concentration of a therapeutic agent or its derivatives and conjugates in biological samples, and further have therapeutic uses in treatment for potential toxicity associated with stable therapeutic conjugates and derivatives, both in vivo and ex vivo.

Imines of the type R-N=CHCO2Et can be coerced into undergoing a (4+2) cycloaddition with substituted dienes if the reaction is carried out in DMF in the presence of both water and acid; these reactions show extremely high regio- and diastereoselectivity.U
