摘要

A new strategy was developed to prepare in a very efficient and convergent manner C- terminal modified tripeptides with high affinities for the Grb2-SH2 domain. Using Pd (PPh3) 2Cl2 as catalyst, selected naphthyl iodides and triflates were coupled to Ac-Pmp (t-Bu) 2- Ac6c-Asn-NH (prop-2-ynyl). The resulting alkyne derivatives were hydrogenated and deprotected to afford potent Grb2-SH2 inhibitors.
