Abstract
A combinatorial synthesis of 24-member RGD models was accomplished on polymer-support. Ortho-, meta-, and para-iodobenzylamines loaded on an aldehyde linker by reductive amination were coupled with RGD sequences and various ω-amino acids by a split-and-pool method. Palladium-catalyzed carbonylative macrolactamization of the polymer-supported cyclization precursors, followed by acid cleavage, provided conformationally restricted RGD model cyclic peptides.Keywords
