Method for preparation of azetidinone-1-oxoacetate by oxidation of the corresponding 2-hydroxyacetate |
| abstract |
A process for production of a 2-azetidinone-1-oxoacetate of the formula <CHEM> useful as an intermediate for preparation of 2-SR<2>-substituted-2-penem-3-carboxylate antibacterial agents; R<1> is a conventional hydroxy protecting group, R<1> is certain carboxy protecting groups and R<2> is (C1-C6)alkyl, <CHEM> and m and n are each 0, 1 or 2; which comprises contacting a corresponding (2-oxo-1-azetidinyl)-N-2-hydroxyacetate ester of the formula <CHEM> with manganese dioxide in a reaction-inert organic solvent at 0-50 DEG C. |
