Use of fluoroform as a source of difluorocarbene in the synthesis of N -CF 2 H heterocycles and difluoromethoxypyridines
摘要:
Fluoroform is used as a source of difluorocarbene to convert various N-, O-, and C-nucleophiles to their difluoromethylated derivatives. Imidazole, benzimidazole, benztriazole, hydroxypyridines, and their derivatives underwent reaction at moderate temperatures and atmospheric pressure, using potassium hydroxide as base in a two-phase (water/acetonitrile) process to provide moderate to good yields of the respective products. Nitrophenols required addition of a co-solvent (methanol) to obtain good yields of products. (C) 2014 Elsevier B.V. All rights reserved.

recruitment in HEK293 cells. Here, we report the chemical synthesis, pharmacological evaluation, and molecular docking studies leading to the identification of two novel noncatechol D1R agonists that are a subnanomolar potent unbiased ligand 19 (PW0441) and a nanomolar potent complete G protein biased ligand 24 (PW0464), respectively. These novel D1R agonists provide important tools to study D1R activation and
非儿茶酚杂环化合物最近被发现是具有优越药代动力学特性的强效和选择性 G 蛋白偏向多巴胺 1 受体 (D1R) 激动剂。为了确定以 G 蛋白或 β-arrestin 信号偏倚为中心的构效关系,围绕先导化合物 5 (PF2334) 的三个芳香药效团采用了系统的药物化学,生成了一系列新分子,这些分子在 D1R Gs- HEK293 细胞中依赖 cAMP 信号传导和 β-抑制蛋白募集。在这里,我们报告了化学合成、药理学评估和分子对接研究,这些研究导致了两种新型非儿茶酚 D1R 激动剂的鉴定,它们是亚纳摩尔强效无偏配体 19 (PW0441) 和纳摩尔强效完全 G 蛋白偏向配体 24 (PW0464),分别。

The present invention provides, in part, compounds of Formula (I) and pharmaceutically acceptable salts thereof; processes for the preparation of; intermediates used in the preparation of; and compositions containing such compounds or salts, and their uses for treating D1 -mediated (or D1 -associated) disorders including, e.g., schizophrenia (e.g., its cognitive and negative symptoms), cognitive impairment (e.g., cognitive impairment associated with schizophrenia, AD, PD, or pharmacotherapy therapy), age-related cognitive decline, dementia, and Parkinson's disease.
exhibited a linear relationship and a reaction parameter (ρ)=+0.56±0.02, which indicated that the trifluoromethylation reaction proceeded via a nucleophilic reactive species. Complex 2 reacts with phenols to produce aryl difluoromethyl ethers in modest‐to‐excellent yields. Mechanisticinvestigations revealed that the difluoromethylation reaction proceeds by initial copper‐mediated formation of difluorocarbene
