ENANTIOSELECTIVE SYNTHESIS OF SILOXYCYCLOPROPANES AND OF γ-OXOCARBOXYLATES BY ASYMMETRIC CATALYSIS
Kunz, Thomas,Reissig, Hans-Ulrich
, p. 2079 - 2082 (1989)
Up to 48percent enantiomeric excess have been attained by cyclopropanation of silyl enol ethers with methyl diazoacetate in the presence of optically active Cu-catalysts.Subsequent ring opening of resulting siloxycyclopropanes gives γ-oxocarboxylates with
