NEW SUBMONOMERS FOR POLY N-SUBSTITUTED GLYCINES (PEPTOIDS)

Abstract Five protected submonomers for peptoid synthesis were prepared, including N in -BOC-tryptamine, O-t -butyl tyramine, PMC-guanidino-propylamine, 6-amino-6-deoxy- d -galactopyranose diacetonide, and 5-amino-2,2-dimethyl-1,3-dioxane. The first three mimic natural aminoacid sidechains i.e. tryptophan, tyrosine, and arginine, while the last two provide hydrophilic sidechains. These submonomers were successfully used for preparation of oligo-peptoids by the submonomer synthesis method.
