Conclusions
The thermocatalytic reaction of ethyl diazoacetate with alkylfurans and the esters of furylcarboxylic acids leads to the formation of the ethyl esters of the corresponding trans, trans 1, 3-alkadien-5-onecarboxylic acids, while reaction with furan leads to the formation of a mixture of a similar ester and 6-ethoxycarbonyl-2-oxabicyclo [3.1. 0]-3-hexene, which is easily isomerized to the former.
