5,5-亚乙基米氏酸及其衍生物的研究进展

Recent Progress of 5,5Ethylene Meldrum's Acid and Its Derivatives

本文综述了５，５－亚乙基米氏酸及其衍生物的合成和化学．５，５－亚乙基米氏酸及其衍生物可通过５，５－二卤代米氏酸、１，１－二羧基环丙烷、５－亚烃基米氏酸、５－（α－硫丁基）米氏酸及胂或铋叶立德来合成；５，５－亚乙基米氏酸及其衍生物可以发生氢化、米氏酸环的开环和环丙烷环的开环或扩环、热解以及异构化等多种反应．

his paper reviews the syntheses and chemistry of 5,5ethylene Meldrum's acid and its derivatives. They could be synthesized from 5,5dihalo Meldrum's acid, cyclopropane 1,1dicarboxylic acid, 5alkene Meldrum's acid, 5(αthiobutyl) Meldrum's acid and arsonium or bismuthonium ylide. Their reactions including hydrogenation, ring opening and /or expansion reaction, pyrolysis and isomerization are also reviewed in this paper.
