2-Siloxy-substituted methyl cyclopropanecarboxylates C - useful building blocks in synthesis - are obtained in great variety and with good yields from the silyl enol ethers E and methyl diazoacetate (D) under copper salt catalysis.Whereas the regiochemical and stereochemical properties of E are completely transferred to the cyclopropanes C, the stereoselectivity concerning the position of the methoxycarbonyl group is low.The 1H and 13C data used to determine the configurations of compounds C are discussed.
