(TMS)ethyl malonate can be generated in-situ by treating potassium ethyl malonate with trimethylsilyl chloride and acylated with aliphatic or aromatic acyl imidazoles or chlorides in the presence of DBU to prepare a variety of β-ketoesters. This constitutes a high yield method for preparing β-ketoesters, which also can be extended to the formation of alkylidene malonates.
