transformation. This reaction features ambient air as the sole oxidant and oxygen source, a broad substrate scope, and excellent functional-group tolerance and proceeds under mild reaction conditions. Furthermore, a highly efficient synthesis of bioactive molecules and natural products including N-methylcrinasiadine, N-isopentylcrinasiadine, N-phenethylcrinasiadine, isoindolo[2,1-b]isoquinolin-5(7H)-one, PJ-34,

An efficient, novel, and environmentally friendly electrochemical regioselective selenylation/oxidation of N-alkylisoquinolinium salts via double C(sp2)–H bond functionalization under undivided electrolytic conditions has been developed. A series of selenide isoquinolones were easily accessed through this sustainable and clean electrochemical system. The present protocol was further extended to afford
已开发了在不分开的电解条件下通过双C(sp 2)-H键官能化对N-烷基异喹啉鎓盐进行高效,新颖且环境友好的电化学区域选择性硒化/氧化的方法。通过这种可持续,清洁的电化学系统,很容易获得一系列硒化异喹诺酮。本方案进一步扩展为提供硒化物喹诺酮和1,3-二甲基-1 H-苯并[ d ]咪唑-2(3 H)-1。此外,抗病毒生物测定法表明化合物3j对烟草花叶病毒(TMV)表现出优异的抗病毒活性,其抑制率高达90%。

based on the privileged tetrahydrobenzazepine scaffold found in many natural products with a wide range of biological properties. This structure was further functionalised with moieties known to possess antioxidative features such as tertiary amine and styrene double bond. A series of eight tetrahydrobenzazepinederivatives of isoquinoline, 3,4‐dihydro‐β‐carboline and pyridine were synthesised employing

scope, low cost, feasibility of scale up, wide availability of reagents, and green reaction conditions, this method shows great potential for preparing isoquinolones and related compounds. The method was applied for atom- and step-economical total synthesis of natural products such as norketoyobyrine.
