摘要
The first example of cyclodextrin dimer appending a macrocyclic polyamine spacer on the primary faces was synthesized via two approaches: 1, a direct reaction of 1,7-bis(2′-aminoethyl)-4,10-dimethyl-1,4,7,10-tetraazacyclododecane (1) with an excess of 6-deoxy-6-O-tosyl-β-cyclodextrin; 2, a condensation of 1 with two equivalents of 6-deoxy-6-formyl-β-cyclodextrin, which wan followed by a reduction with NaBH4.
