It was reported that butyldiethylsilane polystyrene reacted with N-Boc-4-bromophenylalanine under palladium catalyzation to directly form silicon-linker with silicon aryl carbon bond. The peptide chain was elongated by using Boc strategy. And sansalvamide A was obtained by solid phase synthesis using PyBOP (benzotriazole-1-yl-oxy-tris-pyrrolidino-phosphonium hexafluoro- phosphate) as cyclization reagent.

Key words: silicon-linker, sansalvamide A, palladium catalyst, cyclic peptide, solid phase synthesis
