Aplicación

Methylboronic acid can be used as a reagent:
  • In the palladium-catalyzed Stille and Suzuki-Miyaura cross-couplings.[1][2]
  • In the microwave-heated heterogeneous palladium (Pd)-catalytized reactions.[3]
  • In ruthenium (Ru)-catalyzed silylation reactions[4]
  • To prepare bis(aminotropone) titanium (Ti) catalysts for ethylene polymerizations.[5]
  • In the enantioselective asymmetric bromoaminocyclization and bromoaminocyclization using amino-thiocarbamate catalysts.[6][7]
  • To prepare common building blocks for pharmaceuticals and agrochemicals.[8]
  • To prepare chrysin analogs by Suzuki-Miyaura coupling reactions.[9]
  • To prepare casein kinase I inhibitors.[10]
  • In the divergent C-H functionalizations directed by sulfonamide pharmacophores in drug discovery.[2]
  • In the synthesis of unsymmetrical monosulfides from disulfides via copper-catalyzed coupling with boronic acids.[11]
  • In a palladium-catalyzed coupling with enol tosylates.[12]
  • For derivatizing many carbohydrates and biologically active compounds for GLC analysis.

Modern drug discovery is contingent on identifying lead compounds and rapidly synthesizing analogues. The use of a common pharmacophore to direct multiple and divergent C-H functionalizations of lead compounds is a particularly attractive approach. Herein, we demonstrate the viability of

Journal of the American Chemical Society, 133(24), 9164-9167 (2011-05-05)
A facile and efficient enantioselective bromoaminocyclization of unsaturated sulfonamides has been developed using an amino-thiocarbamate catalyst. A range of enantioenriched pyrrolidines were prepared with up to 99% yield and 99% ee. The corresponding lactams could be obtained through oxidation of

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
