A Rh(III)-catalyzed oxidative annulation of pyridin-2(1H)-ones with alkynesviadouble C–H activation to produce highly functionalized 4H-quinolizin-4-ones is disclosed. This reaction features easily available starting materials, simple manipulation, a relatively wide substrate scope, and good functional group tolerance. The application of this protocol is demonstrated by the synthesis of a known fluorescent

A method for the direct C(sp2)–H trifluoromethylation of enamides, including biologically relevant isoindolinones, isoquinolinones and 2-pyridinones using TMSCF3 under oxidative conditions is presented. The protocol is convenient, operationally simple and exhibits high tolerance across a multitude of relevant handles and functional groups.

The reaction of pyridin-2(1H)-ones with PhICl2 and NH4SCN enables an efficient regioselective thiocyanation, leading to the synthesis of the biologically interesting C5 thiocyanated 2-pyridones in good to high yields. The mechanistic pathway of this metal-free approach is postulated to involve the formation of the reactive thiocyanogen chloride from the reaction of PhICl2 and NH4SCN followed with the
吡啶-2(1 H )-酮与PhICl 2和NH 4 SCN 的反应可实现有效的区域选择性硫氰化,从而以良好或高产率合成具有生物学意义的C5 硫氰化2-吡啶酮。这种无金属方法的机械途径被假定为涉及从 PhICl 2和 NH 4 SCN的反应形成反应性氯化硫氰,然后是吡啶-2(1 H )-一个环的区域选择性亲电硫氰化。
<i>N</i>- and <i>O</i>-arylation of pyridin-2-ones with diaryliodonium salts: base-dependent orthogonal selectivity under metal-free conditions
N- and O-arylation reactions of pyridin-2-ones as ambidentnucleophiles have been achieved with diaryliodonium salts on the basis of base-dependent chemoselectivity. In the presence of N,N-diethylaniline in fluorobenzene, pyridin-2-ones were very selectively converted to N-arylated products in high yields. On the other hand, the O-arylation reactions smoothly proceeded with the use of quinoline in chlorobenzene
