A general preparation of polyfunctional hydroxylamine benzoates from the corresponding secondary amines is reported. This convenient synthesis allows the setup of a late-stage functionalization of various secondary amines, including pharmaceuticals and peptidic derivatives. Thus, a cross-coupling of hydroxylamine benzoates with various alkyl-, aryl-, and heteroaryl-zinc chlorides in the presence of

The present disclosure relates to amine-substituted aryl or heteroaryl compounds. The present disclosure also relates to pharmaceutical compositions containing these compounds and methods of treating a disorder (e.g., sickle cell anemia) via inhibition of a methyltransferase enzyme selected from EHMT1 and EHMT2, by administering an amine-substituted aryl or heteroaryl compound disclosed herein or a pharmaceutical composition thereof to subjects in need thereof. The present disclosure also relates to the use of such compounds for research or other non-therapeutic purposes.
A broad range of functionalized aryl- and heteroarylzinc reagents were preparedvia directed zincation of sensitive and moderately activated aromatics and heteroaromatics using TMPZnCl·LiCl under various reaction conditions. Diverse sensitive functional groups such as a nitro group, an aldehyde, an ester, and a nitrile are readily tolerated and are compatible with high metalation temperatures. Furthermore

distinct 5‐6‐6‐ and 5‐7‐6‐fused tricyclic compounds. This chemistry is not only amenable to single compound synthesis, but also to high‐throughput experimentation. It gives easy access to diverse compound arrays with various physicochemical and ADME profiles by fully automated library synthesis. The combination of the high‐throughput experimentation with rapid testing of the compounds in an integrated
Halogenated nucleoside derivatives were trifluoromethylated using a solution of a trifluoromethyl–coppercomplex, which was prepared by shaking trifluoromethyl iodide and copper powder in hexamethylphosphoric triamide and filtering off the excess of copper powder. The following trifluoromethylated nucleosides were obtained in moderate to good yields: 5-trifluoromethyl-uridine, -deoxyuridine, -cytidine
