Diaminodiacid-based synthesis of macrocyclic peptides using 1,2,3-triazole bridges as disulfide bond mimetics

A new approach for the efficient construction of 1,2,3-triazole bridges as disulfide surrogates in peptides, utilizing the diaminodiacid strategy was established. Two thanatin derivatives were prepared with 1,5-and 1,4-disubstituted 1,2,3-triazole diaminodiacids as building blocks. The antibacterial activity studies are also described here.
