Reaction of 1,1-dimethoxy-2-butyne (II) with sodium methoxide in dimethyl sulfoxide at 100° yields (1E)-1,3-dimethoxybutadiene (III) (20–30%). The diene III undergoes ready Diels-Alder reaction with maleic anhydride, N-phenyltriazolinedione and dimethyl acetylenedicarboxylate.
1,1-二甲氧基-2-丁炔(II)与甲醇钠在二甲亚砜中以100°反应生成(1 E)-1,3-二甲氧基丁二烯(III)(20-30%)。二烯III与马来酸酐,N-苯基三唑啉二酮和乙炔二羧酸二甲酯容易进行Diels-Alder反应。
