One-pot synthesis of alternating peptides exploiting a new polymerization technique based on Ugi's 4CC reaction

Abstract

We developed a one-pot synthetic technique for alternating peptides. Central to this technique is a new, catalyst-free polymerization based on Ugi's 4CC reaction. The treatment of imines with the ambident molecules bearing both an isocyanide and a carboxylic acid afforded alternating peptides.
