- Aryl halide and synthesis method and application thereof
-
The invention discloses a synthesis method of aryl halides (including aryl bromide shown as a formula (2) and aryl iodide shown as a formula (3)). All the systems are carried out in an air atmosphere,visible light is utilized to excite a substrate or a photosensitizer to catalyze the reaction; and in a reaction solvent, when aromatic hydrocarbon shown in the formula (1) and sodium bromide serve as raw materials, aryl bromide shown in the formula (2) is obtained through a reaction under the auxiliary action of an additive (protonic acid); or when aromatic hydrocarbon shown in the formula (1) and sodium iodide are used as raw materials, under the auxiliary action of an additive (protonic acid), aryl iodide shown in the formula (3) is obtained through reaction. The synthesis method has the advantages of cheap and accessible raw materials, simple reaction operation and mild reaction conditions. The method is compatible with the arylamine which is liable to be oxidized. The invention provides a new method for the synthesis of aryl halides, realizes the amplification of basic chemicals aryl halides including aryl bromide shown in the formula (2) and aryl iodide shown in the formula (3),and has wide application prospect and practical value.

- Visible-light-promoted oxidative halogenation of (hetero)arenes
-
Organic halides are critical building blocks that participate in various cross-coupling reactions. Furthermore, they widely exist as natural products and artificial molecules in drugs with important physiological activities. Although halogenation has been well studied, to the best of our knowledge, studies focussing on sensitive systems (e.g.aryl amines) have not been reported. Herein, we describe a compatible oxidative halogenation of (hetero)arenes with air as the oxidant and halide ions as halide sources under ambient conditions (visible light, air, aqueous system, room temperature, and normal pressure). Moreover, this protocol is practically feasible for gram-scale synthesis, showing potential for industrial application.

- Rapid preparation of triazolyl substituted NH-heterocyclic kinase inhibitors via one-pot Sonogashira coupling-TMS-deprotection-CuAAC sequence
-
The one-pot, three-component Sonogashira coupling-TMS-deprotection-CuAAC ("click") sequence is the key reaction for the rapid synthesis of triazolyl substituted N-Boc protected NH-heterocycles, such as indole, indazole, 4-, 5-, 6-, and 7-azaindoles, 4,7-diazaindole, 7-deazapurines, pyrrole, pyrazole, and imidazole. Subsequently, the protective group was readily removed to give the corresponding triazolyl derivatives of these tremendously important NH-heterocycles. All compounds have been tested in a broad panel of kinase assays. Several compounds, 8f, 8h, 8k, and 8l, have been shown to inhibit the kinase PDK1, a target with high oncology relevance, and thus they are promising lead structures for the development of more active derivatives. The X-ray structure analysis of compound 8f in complex with PDK1 has revealed the detailed binding mode of the molecule in the kinase. The Royal Society of Chemistry 2011.
