摘要:A novel synthesis reaction for highly stereospecific tri- and tetra-substituted olefins is described. A single stereoisomer of stable α-halo-α,β-ester is produced in high yield by the reaction of aldehyde or ketone with a trihalogenated compound such as trichloroacetate in the presence of CrCl 2 in a solvent. By varying the amount of CrCl 2 used, the stable dihalohydrin intermediate may be obtained as well.

标 题 :Synthesis of glufosinate using an amidase-based process
发明人：ZIMMERMANN GUNTHER; POTT MORITZ STEFAN
权利人:BASF SE
摘要:The present invention relates to a method of preparing glufosinate, comprising the steps of hydrolysing an N-carbamoyl glufosinate amide with an Amidase enzyme to form an N- carbamoyl amino acid compound followed by cleaving off the carbamoyl moiety of said N- carbamoyl amino acid compound.

标题 :Synthesis of fluorinating agents
发明人：CLEMENT MANDY
权利人:F2 CHEMICALS LTD; CLEMENT MANDY
摘要:The invention provides a method for the preparation of an acyl hypofluorite (I), the method comprising treating a mixture comprising a lower nitrile and a carboxylic acid with elemental fluorine. The preferred acyl hypofluorite is acetyl hypofluorite, the corresponding carboxylic acid is acetic acid, and the preferred nitrile is acetonitrile. The reaction is preferably carried out in a single phase on a continuous basis at room temperature, by treating a mixture of nitrile and carboxylic acid with a stream containing 10% fluorine gas in an inert gas such as nitrogen.

摘要:An object of the present invention is to identify an enzyme having activity of synthesizing dihydrotentoxin that is a tentoxin precursor and an enzyme having activity of synthesizing tentoxin using dihydrotentoxin as a substrate. The present invention concerns a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 16 and having activity of nonribosomal peptide synthesis of dihydrotentoxin and a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 18 and having activity of converting dihydrotentoxin to tentoxin.
