A new, simple and short route to 2-(6-methoxycarbonylhexyl)-cyclopent-2-en-1-one(overall yield: 33%) starting from ethyl-10-undecenoate is reported. The main feature of this synthesis is a new cobalt-catalyzed carbonylation of the intermediate epoxide, which occurs with satisfactory yield under very mild conditions.
报道了一种从乙基-10-十一烯酸酯出发的新颖、简单且短的合成路线,用于合成2-(6-甲氧基羧基六基)-环戊-2-烯-1-酮(总产率:33%)。该合成的主要特点是对中间体环氧化物的新型钴催化羰基化反应,该反应在非常温和的条件下以令人满意的产率进行。
