Disclosed are compounds and methods for treating inflammatory and fibrotic disorders, including methods of modulating a stress activated protein kinase (SAPK) system with an active compound, wherein the active compound exhibits low potency for inhibition of the p38 MAPK; and wherein the contacting is conducted at a SAPK-modulating concentration that is at a low percentage inhibitory concentration for inhibition of the p38 MAPK by the compound. Also disclosed are derivatives and analogs of pirfenidone, useful for modulating a stress activated protein kinase (SAPK) system.
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
An unusual rearrangement involving 5-bromo-1-phenylpyridone during its methyl cross coupling with turbo-Grignard reagent, leading to a 5-bromopyridone-fused seven-membered carbocyclic ring
The structure of a cyclohepta[c]pyridin-1-one, a product of an unusual transformation, isolated during a turbo-Grignard reagentpromoted methyl cross coupling to 5-bromo-1-phenyl-2-pyridone, was determined by 1H and 13C NMR, COSY and high-resolution MS, as well as computer modeling. Its formation suggests a remarkable nucleophilic attack at the α-position to the pyridone carbonyl group. A rational pathway
环庚基[ c ]吡啶-1-酮的结构由涡轮和格氏试剂促进了甲基交叉偶联至5-溴-1-苯基-2-吡啶酮的过程中分离,该结构由1 H和1 H确定。13 C NMR,COZY和高分辨率MS以及计算机建模。它的形成表明在吡啶酮羰基的α位上发生了明显的亲核攻击。提出了一个合理的途径。
Rh(III)-Catalyzed Weakly Coordinating 2-Pyridone-Directed Oxidative Annulation Using Internal Alkynes: A Reversal in Selectivity
A rhodium(III)-catalyzed Satoh–Miura type oxidative annulation of N-aryl 2-pyridone derivatives is described using internal alkyne as a coupling partner. A weakly coordinating carbonyl group of the 2-pyridone ring is utilized for this transformation. The reaction proceeds with a broad scope and wide functional group tolerance. The solvent plays an important role in the developed method to furnish a
