  Synthetic receptors for uronic acid salts based on bicyclic guanidinium and deoxycholic acid subunits

  摘要：

  Four receptors for uronic acid salts have been prepared using a chiral bicyclic guanidinium unit and deoxycholic acid derivatives as building blocks. Binding constants in CD3CN/CDCl3 ranged from 3200 to 7000 M-1 for glucuronate and galacturonate salts. Nordeoxycholic-containing receptors were found more efficient and moderately selective for glucuronic salts. (C) 1997 Elsevier Science Ltd.
