• The syntheses of 6‐alkenyl‐5‐ethoxycarbonyl‐2,3‐dihydro‐4H‐pyran‐4‐one derivatives by acylation of γ,β‐unsaturated β‐keto esters or by diacylation of ethyl hydrogen malonate with α,β‐unsaturated acyl chlorides are described. These compounds were converted to 4,5‐dioxo‐2,3,7,8‐tetrahydro‐4H,5H‐pyrano[4,3‐b]pyran derivatives.
