Abstract
The synthesis of a range of racemic 1-acyl-2-vinylcyclopropanes by using two different methodologies is studied. We have developed a copper-catalyzed process for converting diazoketones into 1-acyl-2-vinylcyclopropanes and a sulfur-ylide-mediated procedure which allows, in only two steps, a simplified access to 1-acyl-2-vinylcyclopropanes with alkyl or aryl substituents on the alkene moiety.

1-酰基-2-乙烯基环丙烷的合成:利用铜-类胡萝卜素与硫代内酯的方法学
摘要
研究了使用两种不同方法合成一系列外消旋1-酰基-2-乙烯基环丙烷的方法。我们已经开发出了一种铜催化的方法,用于将重氮酮转化为1-酰基-2-乙烯基环丙烷,以及由硫代叶酸介导的方法,该方法仅需两个步骤即可简化烷基或芳基生成1-酰基-2-乙烯基环丙烷的过程。烯烃部分上的取代基。
