In this paper, we successively apply the "fluorous biphase system" (FBS) technique to the reactions of cyclopropyl aryl ketones with alpha-ketoacetic acids catalyzed by C8F17SO3H (30 mol%) using perfluorodecalin (C10F18, cis- and trans-mixture) and DCE as a co-solvent to give the corresponding products 5,6-dihydropyran-2-ones in good yields. Moreover, the reaction system can be performed for several
在本文中,我们先后将“
氟双相体系”(FBS)技术应用于环丙芳基酮与C8F17SO3H(30 mol%)使用
全氟萘烷(
C10F18,顺式和反式混合物)催化的α-酮
乙酸的反应中。 DCE作为助溶剂,以高收率得到相应的产物5,6-二氢
吡喃-2-酮。而且,反应系统可以进行几次而无需重新装载催化剂和
氟溶剂。
