    3‐(trihalomethylated‐1,2‐azol‐3‐yl)propanoate is reported. Preparation of the key methyl 7,7,7‐trihalo‐4‐methoxy‐6‐oxohept‐4‐enoate precursors from levulinic acid is also described. The synthetic potential of this synthetic protocol was indicated by the production of several methyl and ethyl 3‐(isoxazol‐3‐yl)propanoates and 3‐(1H‐pyrazol‐3‐yl)propanoates, and the respective acid derivatives, in good (70–95%)
