Chen, Yiding published the artcileDirect Copper-Catalyzed Three-Component Synthesis of Sulfonamides, Quality Control of 371766-08-4, the publication is Journal of the American Chemical Society (2018), 140(28), 8781-8787, database is CAplus and MEDLINE.
Sulfonamides such as N-(phenylsulfonyl)morpholine were prepared in one step by coupling of aryl-, heteroaryl-, and alkenylboronic acids such as phenylboronic acid with cyclic and acyclic alkyl secondary amines such as morpholine and primary anilines and the bis(sulfur dioxide) complex of DABCO (DABSO) in the presence of Cu(OTf)2 and 4,4′-dimethoxy-2,2′-bipyridine in DMSO. The method was used on gram scale and was used to prepare sulfonamides from drugs and drug fragments.
