以Pd(PPh3)Cl2/CuI为催化剂,K2CO3为碱,在THF中实现了芳基碘与丙炔酸乙酯(2)的Sonogashira偶联反应,合成了两个新型的芳基丙炔酸乙酯类化合物。而芳基硼酸与2的反应则是在Cu I/Ag2O的催化下,以Cs2CO3为碱,在DCE溶剂中经Suzuki偶联实现的。化合物的结构经1H NMR,13C NMR和HR-MS表征。
Two novel aryl ethyl propynoate compounds were synthesized by Sonogashira reaction of ethyl propiolate(2) with aryl iodides in THF, using Pd(PPh3 )CI2/CuI as catalyst and K2CO3 as alkali. Three aryl ethyl propynoate compounds were obtained by Suzuki cross-coupling of 2 with arylboronic acids in DCE, using CuI/Ag20 as catalyst and Cs2CO3 as alkali. The structures were characterized by 1H NMR, 13C NMR and HR-MS.
