摘要/Abstract

通过钌催化的亚胺酯C—H官能化/环化串联反应为高效构建乙烯基取代的二氢异喹诺酮衍生物提供了新方法.该反应具有较好的官能团耐受性，以中等至良好的收率得到相应的产物.该方法首次实现了钌（II）催化的亚胺酯C—H官能化与4-乙烯基-1，3-二噁烷-2-酮的环化串联反应合成3-乙烯基-3，4-二氢异喹啉-1（2H）-酮.

An efficient and powerful approach for the construction of vinyl-substituted dihydroisoquinolone derivatives through ruthenium-catalyzed tandem C—H functionalization/annulation of imidates has been demonstrated. Various substituted functional groups of imidates could be well tolerated in this new transformation, delivering the corresponding products in moderate to good yields. This method represents the first successful example of Ru(II)-catalyzed C—H functionalization/an-nulation of imidates with 4-vinyl-1,3-dioxolan-2-one to the efficient synthesis of 3-vinyl-3,4-dihydroisoquinolin-1(2H)-ones.
Key words: vinyl-substituted dihydroisoquinolone, ruthenium-catalysis, C-H functionalization, imidate, 4-vinyl-1,3-di-oxolan-2-one
