synthesis of cyclicsulfinates and sulfinamides based on intramolecular homolyticsubstitution (SHi) at the sulfuratom by aryl or alkyl radicals is described. Both alkyl and benzofused compounds can be accessed directly from easily prepared acyclic precursors. Enantiomerically enriched sulfur‐based heterocycles were formed through an SHi process with inversion of configuration at the sulfuratom. Cyclization
描述了基于在硫原子上被芳基或烷基自由基的分子内均质取代(S H i)合成环状亚磺酸酯和亚磺酰胺的通用且有效的方法。烷基和苯并稠合的化合物都可以直接从容易制备的无环前体中获得。对映体富集的硫基杂环是通过S H i过程形成的,硫原子上的构型反转。前手性自由基的环化进行的立体化学结果各不相同,具体取决于传入自由基的大小。2-吡啶基和2-喹啉基会生成联芳基化合物,这是由于攻击芳基亚磺酸盐的邻位而不是亲硫取代引起的。

This disclosure relates to inhibitors of NTRK that are active against wild-type NTRK and its resistant mutants, such as compounds of Formula (I):
In a continuing effort to develop highly potent azole antifungal agents, the three-dimensional quantitative structure-activity relationship methods. CoMFA and CoMSIA, were applied using a set of novel azole antifungal compounds. The binding mode of the compounds at the active site of lanosterol 14 alpha-demethylase was further explored using the flexible docking method. Various hydrophobic, van der Waals,pi-pi stacking, and hydrogen bonding interactions were observed between the azoles and the enzyme. Based on results from the molecular modeling, a receptor-based pharmacophore model was established to guide the rational optimization of the azole antifungal agents. Thus, a total of 57 novel azoles were designed and synthesized by a three-step optimization process. In vitro antifungal assay revealed that the antifungal activities of these novel azoles were greatly improved, which confirmed the reliability of the model from molecular modeling.

An efficient method for the solution-phase parallel synthesis of 4-substituted-1,4-dihydroisoquinolin-3-ones is developed. The isoquinolinones were constructed employing an intramolecular Heck reaction, providing full regio- and stereoselectivity. Most of the synthesized compounds showed potent antiproliferative activities against tumor cell lines.
