Procedure
Following the procedure described for the preparation of 8-oxo-7-acetoxymethylene-2,2-dimethyl-3-oxa-1-azabicyclo[4.2.0]octane from 8-oxo-2,2-dimethyl-3-oxa-1-azabicyclo[4.2.0]octane and using N,N-dimethylacetamide instead of N,N-dimethylformamide one obtains 8-oxo-7-(1'-acetoxyethylidene)-2,2-dimethyl-3-oxa-1-azabicyclo[4.2.0]octane.
