late-stage arylation of N–S bonds in sulfonamides has been developed with using readily available imines as sulfonyl radical source. Diverse complex sulfones could be synthesized by prefunctionalizaiton and subsequent N–S bond arylation, demonstrating the advantages of using sulfonamides as sulfonylation reagents. Additionally, the mechanism research revealed that probably both EDA complex chemistry and photoredox
reactive and/or nonvolatile reagents (anisole, xylenes, mesitylene) expeditious conditions (short reaction time at constant MW power without control of the temperature) were used. With less reactive and/or low-boiling reagents (benzene, toluene, halobenzenes), the rise in temperature and the increase of reaction time were controlled either by sequential MW irradiation or by a temperature order. It was shown

An efficient and concise method for the synthesis of diverse substituted sulfones was developed with high selectivity. Using n-PrOH as the solvent, diaryl sulfones are formed even on a gram scale via metal-free coupling from sulfonyl hydrazines with symmetrical or unsymmetrical diaryliodonium salts.

This invention concerns quinazoline analogs of Formula I:
where an A group is bonded to at least one of the carbons at the 5, 6, 7 or 8 position of the bicyclic ring, and the ring is substituted by up to three independent R
3
groups. The invention also includes methods of using these compounds as type I receptor tyrosine kinase inhibitors and for the treatment of hyperproliferative diseases such as cancer.
