[EN] PYRIMIDINE OR PYRIDINE DERIVATIVE AND MEDICINAL USE THEREOF [FR] DÉRIVÉ DE PYRIMIDINE OU DE PYRIDINE ET SON UTILISATION MÉDICINALE [ZH] 嘧啶或吡啶类衍生物及其医药用途
A one-pot I2-mediated annulation reaction of substrates containing diamino groups and aldehydes has been developed viaoxidativeC–Nbondformation. This general and environmentally benign synthetic approach provides facile access to a variety of 1,3-diazaheterocyclic compounds, including quinazolinones, benzimidazoles, and cyclic amidines.
The present invention relates to compounds that inhibit of focal adhesion kinase function, processes for their preparation, pharmaceutical compositions containing them as the active ingredient, to their use as medicaments and to their use in the manufacture of medicaments for use in the treatment in warm-blooded animals such as humans of diseases such as cancer.

pyridine compounds from a common starting material. The C-4/C-2 approach uses palladium-mediated coupling reactions to sequentially functionalizeC-4 and then C-2. An alternative C-2/C-4 route uses a regioselective SNAr reaction to first substitute at C-2 then subsequently at C-4 by a palladium-mediated reaction. Both approaches have been used successfully to provide a range of 2,4-bis-aminoaryl pyridine

identified as sustainable methine sources for synthesizing quinazolinone and benzimidazole derivatives using a combination of TsOH·H2O/O2 and appropriate bis-nucleophiles for the first time. Deuterium labeling studies clearly proved that the C2 hydrogen of the synthesized heterocycles came from the methine source. These unique reaction conditions were successfully applied to the synthesis of echinozolinone
首次将TsOH·H 2 O / O 2和适当的双亲核试剂组合使用,将醇和醚确定为可持续的次甲基来源,用于合成喹唑啉酮和苯并咪唑衍生物。氘标记研究清楚地证明了合成杂环的C 2氢来自次甲基。这些独特的反应条件已成功地用于合成棘金龙酮(2e'),2f'(rutaecarpine和(±)evodiamine的常见前体)和二咪唑(6d)。该方法的显着特征包括低毒性,使用商业原料作为底物,成本低,对官能团的耐受性强以及对多种双亲核起始原料的适用性。
