摘要
Pure 2-keto-3-deoxy-ulosonic acids, KDGal (1), DAH (2) and its 5-epimer (3) were prepared on preparative scales through diastereoselective aldol reactions of pyruvate respectively with D-glyceraldehyde, D-erythrose and D-threose, catalyzed by Aspergillus terreus extracts; from 2-deoxy-D-ribose, 5-deoxy-KDO (4) could be obtained in a lower yield, with a diastereomeric excess of 72%.
