Synthesis of reduced collagen crosslinks

Van den Nieuwendijk, Adrianus M.C.H.,Benningshof, Jorg C. J.,Wegmann, Volker,Bank, Ruud A.,Te Koppele, Johan M.,Brussee, Johannes,Van der Gen, Arne

, p. 1673 - 1676 (2007/10/03)

A new synthetic route to reduced collagen crosslinks (LNL and HLNL) is described in this report. It enables an enantioselective synthesis of LNL. HLNL was obtained as a mixture of two diastereoisomers. This method also provides the possibility to introduce radio-labels during the synthesis.
