以3,4-二溴环戊砜(1)为原料, 在无水吡啶作用下发生消除反应, 得到反应中间体4-溴-2-环戊烯砜(2), 再分别与一系列取代苯甲酸盐3a～3c以及茜素黄GG (3d)发生酯化反应, 合成出4种新环戊烯砜衍生物4a～4d, 并用IR, 1H NMR, MS, 元素分析等表征了它们的结构.

3,4-Dibromosulfolane (1) was treated with pyridine to form 4-bromo-2-sulfolene (2) by elimination reaction. 4-Bromo-2-sulfolene (2) reacted with substituted benzoic acid salts 3a～3c or alizarin yellow (3d) to give four novel allylic substitution products 4a～4d by esterification reaction, respectively. These novel compounds 4a～4d were determined by IR, 1H NMR, MS spectra and elemental analysis.

Key words: substituted benzoic acid salt, alizarin yellow, esterification, 4-bromo-2-sulfolene, 3,4-dibromosulfolane
