ABSTRACT A method has been worked out to synthetize hitherto unknown 5-(2-chloroalkyl) Meldrum's acids 4 starting from easily accessible 2-chlorocarboxylic acid chlorides 1 in a two-step reaction. Reactions of dihaloethane and Meldrum's acid in the presence of potassium carbonate and the usefulness of compounds 4 are also presented.
摘要 已经制定了一种方法来合成迄今为止未知的 5-(2-氯烷基) Meldrum 酸 4,从容易获得的 2-氯甲酰氯 1 开始,在两步反应中。还介绍了二卤乙烷和 Meldrum 酸在碳酸钾存在下的反应以及化合物 4 的用途。
