A convenient and general microwave-assisted method for the synthesis of stereochemically defined α-methylalkenoic acids and esters from allylic phosphonium salts in a basic aqueous medium is described. A selective preparation of acids or esters was dependent on the base (NaOH or NaHCO3) employed in the reaction and could be achieved with good to excellent yields under mild conditions in the absence
描述了一种方便和通用的微波辅助方法,用于在碱性水介质中从烯丙基鏻盐合成立体化学定义的 α-甲基链烯酸和酯。酸或酯的选择性制备取决于反应中使用的碱(NaOH 或 NaHCO3),并且可以在不存在氢化物和还原剂的温和条件下以良好到极好的收率实现。© 2012 Wiley Periodicals, Inc. 杂原子化学 23:179–186, 2012; 在 wileyonlinelibrary.com 上在线查看这篇文章。DOI 10.1002/hc.21001
