A large number of 3-oxo esters can be accessed by condensation of ethyl diazoacetate with aldehydes. Two variations are worth mentioning, the nucleophilic addition of lithiated diazo esters and the Lewis acid catalyzed condensation of ethyl diazoacetate with aldehydes. The overall mechanism of these reactions is probably like that for ketones (see Section, Scheme 91).
