Abstract

We have developed a practical, general protocol for denitration of readily available α‐nitroketones with sulfur and amines to access a broad range of α‐ketothioamides under mild conditions. Such a reaction proceeds under metal‐, oxidant‐, and catalyst‐free conditions to provide synthetically useful α‐ketothioamides. Furthermore, the mild reaction conditions tolerate a wide range of substrates especially for the synthesis of aliphatic α‐ketothioamides which are rarely reported. [ABSTRACT FROM AUTHOR]

Abstract

A new, metal-free method for the formation of C(sp3)-O bonds was established by PhI(OAc)2-mediated oxygenation of benzylic C(sp3)-H bonds with N-hydroxyamides at room temperature, in which the C(sp3)-H oxidation is activated by a polyflurophenylamide group. [ABSTRACT FROM AUTHOR]
