Synthesis Based on Affinity Separation (SAS): Separation of Products Having Barbituric Acid Tag from Untagged Compounds by Using Hydrogen Bond Interaction
A new method is described for affinity purification of synthetic compounds based on molecular recognition between bis(2,6-diaminopyridine)amide of isophthalic acid and a barbituric acid derivative. The desired compounds possessing the barbituric acid derivative as a tag were readily isolated from the reaction mix- ture by the following procedure. After each reaction cycle, the reac- tion mixture was
