Cyclic homooligomers of mannose-derived furanoidsugaraminoacid 1 [H-Maa(Bn(2))-OH] were synthesized by using BOP reagent in the presence of DIPEA under dilute conditions that converted the sugaraminoacid monomer directly into its cyclic homooligomers 3a and 4a. The glucose-based sugaraminoacid 2 [H-Gaa(Bn(2))-OH] under the same reaction conditions gave a bicyclic lactam 5a as the major product
