## Abstract As an active diene (more active than furan itself), 3,4‐dimethoxyfuran (**1**) affords with many dienophiles the respective cycloadducts in a high yield [2]. It has recently been found that under thermal conditions **1** easily reacts with maleic anhydride and its monomethyl derivative,
