Background: α-Methylene cycloalkanones are considered of interest because of their biological
activity. Herein, in this paper the synthesis of (±) HomoSarkomycine Esters was described and
characterized.
Methods: Using Bylis-Hillman adducts, triethlorthoacetate and propanoic acid, (±) HomoSarkomycine
Esters could be synthesized by smoothly Johnson-Claisen rearrangement.
Results: A small library of target compounds was prepared under optimized reaction conditions in
moderate yields. The reaction mechanism and the DFT study have been investigated.
Conclusion: This methodology provides ready access to 2-hydroxymethyl-2-cyclopentenone 1a which
can be served as the raw materials of the synthesis of (±) HomoSarkomycine Ester.
