title: Olefin metathesis in the design and synthesis of a globally constrained Grb2 SH2 domain inhibitor.
abstract: One drawback frequently associated with olefin metathesis-mediated peptide macrocyclization, the loss of side chain functionality at sites of ring closure, may be circumvented by incorporation of side chain functionality within the ring-closing olefin segments. This approach is demonstrated in the preparation of a macrocyclic Grb2 SH2 domain antagonist designed as a conformationally constrained beta-bend mimic.
