(3S,4R)-4-Acetoxy-3-[(R)-1-(tert-butyldimethylsilyloxy)ethyl]azetidin-2-one Usage And Synthesis
Chemical Propertieswhite to light yellow crystal powde
UsesAn acetoxyazetidinone derivative used as an intermediate in the preparation of carbapenem antibiotics.
Purification MethodsPurify it by chromatography on silica gel (3 x 14cm) for 50g of ester using 20% EtOAc in n-hexane. The eluate is evaporated, and the residue is recrystallised from hexane (white fluffy crystals). [Leanza et al. Tetrahedron 39 2505 1983.]
