Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner.26978-64-3, Name is 4-Hydroxybutane-1-sulfonic acid, SMILES is O=S(CCCCO)(O)=O, belongs to thiazines compound. However, they have proven to be challenging because of the mutual inactivation of both catalysts. In a document, author is Soria-Castro, Silvia M., introduce the new discover, Formula: C4H10O4S.
Versatile one-pot synthesis of benzo-fused thiacycles by copper catalysis
A novel, one-pot synthesis of structurally diverse benzo-fused thiacycles via a Cu-catalysed intermolecular C-S coupling/cyclisation tandem process, employing the same catalytic system, has been developed. Thus, 3,4-dihydro-2H-benzo[e][1,3]thiazines and 4H-benzo[e][1,3] thiazines were selectively obtained by this one-pot tandem process from (2-iodophenyl) methanamine and aldehydes or 1-(azido-methyl)-2-iodobenzene, respectively. These reactions proceeded in toluene at 100 degrees C with potassium thioacetate, thiobenzoate or ethyl xanthogenate in moderate to good isolated yields. The first one avoids the imine isolation step. A similar approach to benzo[b] thiophene derivatives from 2-(2- iodophenyl) acetonitrile was also developed.
