A diethylphosphite mediated electrochemical oxidation strategy for the synthesis of 3,4-dihydroisoquinolin-1(2H)-ones from tetrahydroisoquinolines under mild conditions has been developed. This protocol provides an environmentally friendly and simple way for the construction of C=O bonds in an undivided cell unit.

cycloaddition–aromatization cascade was realized with N-substituted tetrahydroisoquinolines and electron-deficient olefins. Under the mild conditions, the reaction proceeded smoothly and displayed excellent functional group tolerance, affording 5,6-dihydro-pyrrolo[2,1-a]isoquinolines in good to high yields. This protocol exhibits a broad substrate scope to both N-alkyl tetrahydroisoquinolines and dipolarophile
用N-取代的四氢异喹啉和缺电子烯烃实现了高效且环保的CuBr/NHPI共催化好氧氧化[3 + 2]环加成-芳构化级联。在温和条件下,反应顺利进行,并表现出优异的官能团耐受性,以良好至高收率得到5,6-二氢-吡咯并[2,1- a ]异喹啉。该协议对N-烷基四氢异喹啉和亲偶极底物都表现出广泛的底物范围。
