A novel cycloaromatization reaction leading to substituted ethyl 2-hydroxy-3-methylthiobenzoates by condensation ∝-oxoketene dithioacetals with excess of Reformatsky reagent from ethyl bromoacetate through intermediate dienes 3 has been reported.
已经报道了一种新颖的环芳构化反应,该反应通过使β-氧杂环丁烯二硫缩醛与过量的Reformatsky试剂从溴乙酸乙酯通过中间体二烯3缩合而导致生成2-羟基-3-甲基硫代苯甲酸乙酯。
