Artificial Molecular Anion Hosts. Synthesis of a Chiral Bicyclic Guanidinium Salt Serving as a Functionalized Anchor Group for Oxo Anions

Starting from L-asparagine, the synthesis of the S,S-bis(hydroxymethyl)-substituted bicyclic guanidinium salt 3 is described, which is obtained in 20percent overall yield with a diastereomeric excess de >98percent.The guanidinium compound 3 may serve as a
