AN EFFICIENT AND HIGHLY FLEXIBLE SYNTHESIS OF α,β-UNSATURATED γ-OXOESTERS
Boehm, Ingrid,Schulz, Rick,Reissig, Hans-Ulrich
, p. 2013 - 2016 (1982)
Siloxy substituted methyl cyclopropanecarboxylates are cleaved by bromine to afford α-bromo-γ-oxoester and, after treatment with triethylamine, good yields of α,β-unsaturated γ-oxoesters.
