trans- and cis-1-Alkyl-4-aryl-3-chloroazetidin-2-ones, prepared through cyclocondensation of chloroketene and the appropriate imines in a diastereoselective way, were transformed into the corresponding non-activated trans- and cis-2-aryl-3-(hydroxymethyl)aziridines via reductive ring contraction using LiAlH(4) in Et(2)O. Furthermore, trans-2-aryl-3-(hydroxymethyl)aziridines were transformed into 2-amino-3-arylpropan-1-ols and

A new synthetic protocol for the LiAlH(4)-promoted reduction of non-activated aziridines under microwave conditions was developed. Thus, ring opening of 2-(acetoxymethyl)aziridines provided the corresponding beta-amino alcohols, which were then used as eligible substrates in the synthesis of 5-methylmorpholin-2-ones via condensation

Questions

1–5 of 5 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  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

  3. Product 212776, Lithium aluminum hydride solution, appears to container a precipitate in it.  Is it still OK to use?

    1 answer

    1. Most if not all solid lithium aluminum hydride will contain some form of insoluble oxides from slight air exposure.  You should be able to filter the insolubles - keeping air exposure to a minimum is the key. This procedure should be done entirely under argon (argon is typically a drier gas than nitrogen). If the final solution is exposed to air at any time, insolubles will be formed which will  then require further filtration to get clear again.

  5. Why is Product 212776, Lithium aluminum hydride solution, considered carcinogenic?

    1 answer

    1. The carcinogen reference comes from Tetrahydrofuran (THF).  The solution is 90% THF.  The THF reference is form the National Toxicology Program (NTP) database.
