## Abstract A substitute for the __Darzens__ glycidic ester synthesis for converting unsaturated ketones or aldehydes into the homologated β,γ‐ or α,β‐unsaturated aldehydes employing sulfur ylides is described. The carbonyl group is converted into the unsaturated oxirane which is then rearranged to
