DIPEA was found to be an excellent sulfur activator to promote the reaction of 2-nitrochalcones with elementalsulfur. A wide range of 2-benzoylbenzothiophenes was obtained as a result of a cascade of alkene C═C bond thiolation, aromatic sulfur-denitration.

日期:2017.7.21
A catalyst-free, redox-neutral, and completely atom-economical synthesis of sultams by simply heating 2-nitrochalcones with elemental sulfur in 3-picoline or N-methylmorpholine is described. The S–N, C–S, and S═O bonds of the sulfonamide are efficiently formed between the nitrogen atom of the 2-nitro group and the α-carbon of the chalcones and elemental sulfur with the migration of two oxygen atoms

key to the neuroinflammatory events and the brain damage associated to stroke. Non-zinc binding ligands are an emerging trend in drug discovery programs in this area due to their lower tendency to show off-target effects. 7-Amino-phenanthridin-6-one is disclosed as a new framework able to inhibit matrix metalloproteinases by binding to the distal part of the enzyme S1’ site, as shown by computational
