reaction first, and then intra-molecular hydroamination of alkyne catalyzed by CuI/o-phen was proved to be an efficient method for the synthesis of imidazo[2,1-a]isoquinoline, phenanthro[9′,10′:4,5]imidazo[2,1-a]isoquinoline and acenaphtho[1′,2′:4,5]imidazo [2,1-a]isoquinoline derivatives in the presence of Cs2CO3.
实验证明,先进行Sonogashira反应,然后再用CuI / o -phen催化炔烃分子内加氢胺化反应是合成咪唑并[2,1- a ]异喹啉,菲咯啉[9',10':4]的有效方法。在Cs 2 CO 3存在下,, 5]咪唑并[2,1- a ]异喹啉和[1',2':4,5]咪唑并[2,1- a ]异喹啉衍生物。
