effective and practical modularflowdesign for the meta-selective C-Harylation of anilines. The design consists of four continuous-flow modules (i.e., diaryliodonium salt synthesis, meta-selective C-Harylation, inline copper extraction, and aniline deprotection) which can be operated either individually or consecutively to provide direct access to meta-arylated anilines. With a total residence time

C(sp3)–H alkylation of 2-methylanilinium saltsvia radical intermediates was developed. The anionic decatungstate photocatalyst ([W10O32]4–) interacts with the ammonium group of the substrate through electrostatic interaction and selectively abstracts a hydrogen atom from the proximal benzylic carbon atom under UV irradiation. A variety of 2-methylanilinium salts reacted with electron-deficient alkenes
开发了通过自由基中间体对 2-甲基苯胺盐进行位点选择性 C(sp 3 )-H 烷基化。阴离子十钨酸盐光催化剂([W 10 O 32 ] 4-)通过静电相互作用与底物的铵基相互作用,并在紫外线照射下选择性地从近端苄基碳原子中提取一个氢原子。多种 2-甲基苯胺盐与缺电子烯烃反应。烷基化产物通过 C-N 键的断裂成功地转化为芳基碘化物,并通过分子内环化成功地转化为四氢苯并氮杂酮衍生物。机理研究清楚地表明 [W 10 O 32 ] 4–和铵基。

The present invention is directed to novel compounds and pharmaceutical compositions that inhibit the binding of the SDF-1 chemokine to the chemokine receptor CXCR4 and/or the binding of the SDF-1 or I-TAC chemokines to the chemokine receptor CCXCKR2 (CXCR7). These compounds are useful in preventing tumor cell proliferation, tumor formation, metastasis, inflammatory diseases, treatment of HIV infectivity, treatment of stem cell differentiation and mobilization disorders, and ocular disorders.

[FR] La présente invention concerne des composés innovants et des compositions pharmaceutiques qui inhibent la liaison de la chimiokine SDF-1 au récepteur des chimiokines CXCR4 et/or la liaison des chimiokines SDF-1 ou I-TAC au récepteur des chimiokines CCXCKR2 (CXCR7). Ces composés sont utilisables dans la prévention de la prolifération des cellules tumorales, de la formation des tumeurs, de la métastase et des maladies inflammatoires, dans le traitement d'une infection par le VIH, dans le traitement des troubles de différenciation et de mobilisation des cellules souches et dans les affections oculaires.
