An approach of general applicability to diverse quinolines and isoquinolines via a tactic that utilizes the recursive anion from nitromethane as a 1C-connector to stitch easily and appropriately crafted pyridyl ynones through a transition-metal-free, tandem Michael addition–SNAr process is delineated. The straightforwardness, one-pot operation, and good yields mark this methodology for wider exploitation
一种普遍适用于各种喹啉和异喹啉的方法,该策略利用来自硝基甲烷的递归阴离子作为1C连接剂,通过无过渡金属的串联迈克尔加成-S N Ar工艺轻松,适当地合成吡啶基炔酮。划定的。简便易行,一锅操作和高收率标志着该方法可用于更广泛的开发,以针对更多修饰的喹啉和异喹啉以及体现这些部分的复杂平台。
