Upon treatment with various organolithiums, 4-acetoxyazetidin-2-one(10) afforded the corresponding carbon-displaced compounds (11),(12), and (13). 4-(3-diazo-3-ethoxycarbonyl-2-oxopropyl)azetidin-2-one (15) was also synthesised from (10) and ethyl α-diazoacetoacetate in the presence of lithium hexamethyldisilazide in one step.The diazo-compound (15) was thermally cyclised to the bicyclic keto-ester (17) in the presence of rhodium acetate.
