variety of substituted quinazolin-4(3H)-ones were prepared in 63-91% yields by the palladium-catalyzed cyclocarbonylation of o-iodoanilines with imidoyl chlorides and carbon monoxide. The reaction is believed to proceed via in situ formation of an amidine, followed by oxidative addition, CO insertion, and intramolecular cyclization to give the substituted quinazolin-4(3H)-ones.

be reported: these narrow bite angle pro-ligands have been used to great effect as ligands in homogeneouscatalysis. We herein demonstrate that terminal alkynes readily undergo double hydrophosphination with HPPh2 and catalytic potassium hexamethyldisilazane (KHMDS) to generate 1,1-diphosphines. A change to H2PPh leads to the formation of P,P-divinyl phosphines.
A robust synthetic method for 2-alkylamino-6-carboxy-5,7-diarylcyclopenteno[1,2-b]pyridines via acylamination at the alpha position of the functionalized pyridine system has been developed. The key step in this method was achieved by treatment of the corresponding pyridine N-oxides with 2.5 equiv of imidoyl chlorides in the presence of triethylamine, thus producing the desired 2-acylaminopyridines
已经开发了通过在官能化吡啶系统的α位上的酰化作用来合成2-烷基氨基-6-羧基-5,7-二芳基环戊烯[1,2- b ]吡啶的稳健合成方法。该方法的关键步骤是在三乙胺存在下,用2.5当量的亚氨酰氯处理相应的吡啶N-氧化物,从而以较高的收率(74-96%)产生所需的2-酰基氨基吡啶。
