  Conversion of Glucuronic Acid Glycosides to Novel Bicyclic β-Lactams

  摘要：

  GRAPHICSMethodology for the conversion of glucuronic acid glycosides to novel bicyclic beta-lactams is reported. Using this strategy, we prepared two novel templates suitable for use in combinatorial chemistry strategies for the construction of a number of interesting beta-lactam motifs. Key features of this strategy include a diastereoselective Ferrier reaction of a glucuronic acid glucal, selective beta-lactam ring formation using a cyclic allylic alcohol, and a chemoselective benzylic oxidation.
