A novel tunable regioselective synthesis of pyrazolo[3,4-d]pyrimidine derivatives via aza-Wittig/Ag(i) or base-promoted tandem reaction has been developed. This approach provides a simple and efficient way to construct pyrazolo[3,4-d]-pyrimidine derivatives under mild conditions. This journal is © 2015 The Royal Society of Chemistry. Source

A copper-catalyzed oxidative coupling between quinazoline 3-oxides and unactivated aldehydes was described. The reaction worked well for both aliphatic and aromatic aldehydes and produced not only the direct oxidative coupling ketones but also cyclic hydroxamic esters derived from quinazolines. © The Royal Society of Chemistry 2016.

Established herein is an efficient direct oxidative acylation of sulfoximines with methylarenes as an acyl donor. Electron-donating as well as -withdrawing groups on the methylarenes are tolerated and even steric demanding ortho substituents are compatible. Both coupling partners are used in their native form, thus obviating prior functionalization and activation. © The Royal Society of Chemistry 2015. Source

A direct oxidative amidation between methylarenes and aqueous ammonia using a tert-butyl hydroperoxide and tetrabutylammonium iodide (TBHP/TBAI) oxidation system with co-catalysis of iron(III) chloride has been developed. Both coupling partners were used in their native form to render prior functionalization unnecessary and afford a facile approach to aromatic primary amides. © 2015 WILEY-VCH Verlag GmbH & Co.

An environmentally friendly direct oxidative amidation between methylarenes and free amines was developed. The aromatic amide could be prepared efficiently from raw chemicals by employing TBHP as a "green" oxidant with co-catalysis of TBAI and FeCl3 in water. © The Royal Society of Chemistry 2015. Source
