Mechanochemical synthesis of aromatic sulfonamides
Mkrtchyan, Satenik,Iaroshenko, Viktor O.
supporting information, p. 11029 - 11032 (2021/11/03)
A three-component Pd-catalysed aminosulfonylation reaction of K2S2O5 and amine with aryl bromides or aromatic carboxylic acids was developed. This strategy was developed to utilise mechanical energy and accommodate primary as well as secondary aliphatic and aromatic amines to provide a new shortcut to a wide range of sulfonamides. Studies on the scope and limitations of the reaction indicated its tolerance of a vast range of functional groups and many structural patterns. The reactions were scaled up to gram quantities.

A convenient synthesis of sulfonamides from thiols is described. In situ preparation of sulfonyl chlorides from thiols is accomplished by oxidation with trichloroisocyanuric acid (TCCA), benzyltrimethylammonium chloride and water (2.5 equiv). The sulfonyl chlorides are then further allowed to react with excess amine in the same reaction vessel. Triethylamine can be optionally added as acid scavenger. Copyright Taylor & Francis Group, LLC.
Discovery of CGS 27023A, a non, peptidic, potent, and orally active stromelysin inhibitor that blocks cartilage degradation in rabbits
MacPherson, Lawrence J.,Bayburt, Erol K.,Capparelli, Michael P.,Carroll, Brian J.,Goldstein, Robert,Justice, Michael R.,Zhu, Lijuan,Hu, Shou-Ih,Melton, Richard A.,Fryer, Lynn,Goldberg, Ron L.,Doughty, John R.,Spirito, Salvatore,Blancuzzi, Vincent,Wilson, Doug,O'Byrne, Elizabeth M.,Ganu, Vishwas,Parker, David T.

Structure-activity relationships of a lead hydroxamic acid inhibitor of recombinant human stromelysin were systematically defined by taking advantage of a concise synthesis that allowed diverse functionality to be explored at each position in a template. An ex vivo rat model and an in vivo rabbit model of stromelysin-induced cartilage degradation were used to further optimize these analogs for oral activity and duration of action. The culmination of these modifications resulted in CGS 27023A, a potent, orally active stromelysin inhibitor that blocks the erosion of cartilage matrix.
