Synthesis of divalent α-D-mannopyranosylated clusters having enhanced binding affinities towards concanavalin A and pea lectins
Two different α-D-mannopyranosides having aminated heteroaliphatic (2) and p-isothiocyanatophenylated (10) aglycones were prepared and used as key precursors for the conjugation to a 3,5-diaminobenzoic acid core (3) using thiourea and amide coupling chemi
