  3-Thio or amino substituted benzo[b]thiophene-2-carboxamides and 3-oxygen, thio, or amino substituted benzofuran-2-carboxamides are described as agents which inhibit leukocyte adherence to vascular endothelium and, as such, are effective therapeutic agents for treating inflammatory diseases. Certain of these compounds are novel and methods of manufacture are also described. The same benzo[b]thiophene and benzofuran-2-carboxamides also inhibit the activation of human immunodeficiency virus (HIV), latent in infected mammals.

  2-fluorobenzonitriles were converted to the corresponding 3-amino[1]benzothiophenecarboxylic acid esters, which in turn were annulated with formamidine or various equivalents to produce the desired tricyclic benzothienopyrimidines. Various methoxy and nitro/amino substituents were placed on the phenyl ring, requiring several different strategies to prepare the desired benzothiophenes. Several different pyrimidone annulations

  作者：Yao Zhou、Ya Wang、Yixian Lou、Qiuling Song

  DOI：10.1021/acs.orglett.9b02288

  日期：2019.11.15

  We disclose a novel Cu-catalyzed denitrogenative transannulation of 3-aminoindazoles to afford diverse functionalized 3-aminobenzothiophenes and 1-aminoisoquinolines, in which denitrogenative transannulation of 3-aminoindazoles is reported for the first time. This transformation proceeds via an "extrude-and-sew" strategy with an unprecedented radical reactivity of 3-aminoindazoles.
