Research speed reading in 2021. We’ll be discussing some of the latest developments in chemical about CAS: name: 2,3-Dibromobenzo[b]thiophene, C8H4Br2S. A document type is Patent, introducing its new discovery., name: 2,3-Dibromobenzo[b]thiophene
This application relates to novel compounds of formula I (and their pharmaceutically acceptable salts), as defined herein, processes and intermediates for their preparation, pharmaceutical formulations comprising the novel compounds of formula I, and the use of the compounds of formula I as thrombin inhibitors. wherein E is CReor N in which Reis hydrogen, methyl, methoxy or halo; R1is hydrogen or methyl; R2is R2aor R2bin which R2ais -X2-(CH2)n-Rfin which X2is a direct bond, methylene or O; n is 1, 2 or 3; and Rfis 5-tetrazolyl, carboxy, [(1-4C)alkoxy]carbonyl or hydroxymethyl; R2bis -X2-(CH2)m-NRaRbin which X2is a direct bond, methylene or O; m is 1, 2 or 3; provided that when m is 1, then X2is a direct bond; and Raand Rbare independently hydrogen or (1-3C)alkyl or the group NRaRbis pyrrolidino, piperidino or morpholino; R3is -X3-(CH2)s-NRsRtin which X3is a direct bond, methylene or O; s is 1 or 2; provided that when s is 1, then X3is a direct bond; and Rsand Rtare independently hydrogen or (1-3C)alkyl or the group NRsRtis pyrrolidino, piperidino or morpholino; and R6is hydrogen, hydroxy or methoxy.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 6287-82-7 is helpful to your research.
