  Cyclic oligomers (macroaldonolactones) from a protected d-galactonic acid monomer

  摘要：

  Dicyclohexylcarbodiimide-promoted self-condensation of 2,3:4,5-di-O-isopropylidene-D-galactonic acid (3) led to the macrocyclic oligomeric cyclo[(2,3:4,5-di-O-isopropylidene-(1 -> 6)-D-galactonate)(2)] (4) and cyclo[(2,3:4,5-di-O-isopropylidene-(1 -> 6)-D-galactonate)(3)] (5), having, respectively, 14- and 21-membered rings. The macrocycles 4 and 5 were also synthesized by cyclization of the respective linear dinner 11 and trimer 14 omega-hydroxy acids precursors prepared by stepwise additions of 3. Compounds 4 and 5 are biomaterials that may be described as macrolactone-cyclodextrins. (C) 2009 Elsevier Ltd. All rights reserved.
