in structural diversity and allow the rapid assembly of complex products from readily available starting materials. Cascade hydrozirconation-Zr/Zn transmetalation-imine addition of alkynes represents a versatile methodology for the synthesis of (E)-alkene and cyclopropane dipeptide isosteres. Appropriate substitutions at the sp2-carbon of (E)-alkene peptide isosteres allow a range of Pd-catalyzed cross-coupling
