(3S,4R)-4-Acetoxy-3-[(R)-1-(tert-butyldimethylsilyloxy)ethyl]azetidin-2-one Usage And Synthesis

Chemical Properties

white to light yellow crystal powde

Uses

(3S,4R)-4-Acetoxy-3-[(R)-1-(tert-butyldimethylsilyloxy)ethyl]azetidin-2-one is an acetoxyazetidinone derivative used as an intermediate in the preparation of carbapenem antibiotics.

Purification Methods

Purify 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.]
