[GRAPHICS]Reliable and practical synthetic routes for the construction of hybrid molecules bearing both a chelating center and a useful biofunction are presented. They comprise the sequential cross coupling reaction between ethynylated synthons with iodo substituted L-tyrosine derivatives and provide access to various rationally designed chiral ligands.

Palladium-catalysed coupling has been used to attach a series of fluorescent (acridonyl, pyrenyl, fluoresceinyl, dansyl and ruthenium phenanthrolinyl) and enzymic (biotinyl) labels containing a terminal alkyne to electophilic biological molecules based on amino acids, nucleosides and steroids.
