摘要:The present invention relates to non-naturally occurring polypeptides useful for preparing armodafinil, polynucleotides encoding the polypeptides, and methods of using the polypeptides. The non-naturally occurring polypeptides of the present invention are effective in carrying out biocatalytic conversion of the (i) 2-(benzhydrylsulfinyl)acetamide to (−)-2-[(R)-(diphenylmethyl)sulfinyl]acetamide (armodafinil), or (ii) benzhydryl-thioacetic acid to (R)-2-(benzhydrylsulfinyl)acetic acid, which is a pivotal intermediate in the synthesis of armodafinil, in enantiomeric excess.

摘要:The present invention relates to a non-cryogenic process for the large scale synthesis of disentangled ultra high molecular weight polyethylene (DUHMWPE) polymers. The process comprises of the following steps:n a. mixing FI catalyst of formula I nn nwith a hydrocarbon solvent containing poly-methyl aluminoxane (P-MAO) co-catalyst in a vessel under stirring before polymerization or directly in the polymerization vessel at a temperature ranging between 25° C. and 29° C. under a dry Nitrogen atmosphere; and lower concentration of co-catalyst resulting in the associated benefits as described earlier in the claims and descriptions.n b. pressurizing ethylene in the polymerization vessel and polymerizing ethylene in a solution or a suspension, continuously or batch wise, in one or more stages at a temperature is in the range of 30° C. to 50° C.

摘要:This invention contemplates improved methods of enzymatic production of carbohydrates especially fucosylated carbohydrates. Improved syntheses of glycosyl 1- or 2-phosphates using both chemical and enzymatic means are also contemplated. The phosphorylated glycosides are then used to produce sugar nucleotides that are in turn used as donor sugars for glycosylation of acceptor carbohydrates. Especially preferred herein is the use of a disclosed method for fucosylation.
