An operationally simple protocol for direct N- and O-difluoromethylation of 2-pyridones, quinolinones, and isoquinolinones using commercially available TMSCF2Br is disclosed. The chemoselectivity is modulated by simple variations in temperature, solvent, and strength of the base. Diverse, synthetically relevant functional groups are tolerated, including functional groups that have reported reactivity

The scope and limitations of the simple synthesis of functionalized quinolizidin-4-ones by chemoselective N-alkenylation of NH pyridin-2(1H)-ones (2-pyridones), regioselective addition of lithium allyl(di-n-butyl)magnesates(1-) to N-alkenylpyridin-2(1H)-ones, followed by ring closing metathesis (RCM) is described. A number of functionalizations introduced into quinolizidin-4-one rings demonstrated
通过N H吡啶2(1 H)-酮(2-吡啶酮)的化学选择性N-烯基化,区域选择性加成烯丙基锂(二-正丁基)的化学合成N吡啶基简单地合成官能化的喹啉并丁4-酮的范围和局限性将镁酸盐(1-)转变为N-烯基吡啶-2(1 H)-,然后进行闭环复分解(RCM)。引入喹喔啉-4-酮环的许多功能化表明了支架合成中提出的策略的高前景。还介绍了它们扩展到吡啶并[1,2 - a ]氮杂环庚烷-4-酮和吡啶并[1,2 - a ]偶氮星-4-酮衍生物的合成以及螺环稠合化合物的合成。
