Abstract

In the course of a program devoted to the synthesis of small peptidic molecules mimicking the RGD (Arg-Gly-Asp) motif, the allylic animation of enantiomeric ally pure carbonates with 4-substituted benzylamines afforded dehydro-p-amino esters through an S(N)2' mechanism. The reaction performed with 4-aminobenzylamine occurred with complete chemoselectivity, as the aliphatic amine was much more reactive than the aromatic one. This allowed useful precursors of biologically active compounds to be obtained, avoiding extra protection-deprotection steps. The same reaction performed on glycine-derived amides gave similar results, allowing a novel type of RGD mimetic to be prepared, whose ability to inhibit cell adhesion was found to be very promising.
