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:Process for the preparation of acyl cyanide compounds
发明人：FINDEISEN KURT; KRAETZER HANS; LENTHE MANFRED
权利人:BAYER AG
摘要:This invention relates to a new process for the preparation of acyl cyanides of the general formula n n R.sup.1 --CO--CN (I) n n wherein R 1 is an optionally substituted alkyl radical up to 18 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 12 carbon atoms, an optionally substituted aryl radical or an optionally substituted 5- or 6-membered heterocyclic radical, which can additionally also be fused with a benzene ring, which process comprises reacting a carboxylic acid anhydride of the formula n n R.sup.1 --CO--O--CO--R.sup.1 (II) n n with an alpha-hydroxynitrile of the formula ##STR1## in which R 2 and R 3 are identical or different and represent a hydrogen atom, an optionally substituted alkyl radical with 1 to 18 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 12 carbon atoms, an optionally substituted aryl radical or an optionally substituted 5- or 6-membered heterocyclic radical, which can additionally also be fused with a benzene ring. The acyl cyanides (I) are known compounds and can be used as starting material for the synthesis of herbicides.

标题 :Process for the preparation of acyl cyanides
发明人：KLAUKE ERICH; FINDEISEN KURT
权利人:BAYER AG
摘要:A novel process for the preparation of acyl cyanides of the general formula R-CO-CN (I) wherein R represents an optionally substituted alkyl radical with 1 to 8 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 12 carbon atoms, an optionally substituted aryl radical or an optionally substituted 5-membered or 6-membered heterocyclic radical, which can additionally be fused to a benzene ring, in which a carboxylic acid fluoride or the general formula R-CO-F (II) in which R has the abovementioned meaning is reacted with an alkali metal cyanide, optionally in the presence of a diluent, at a temperature between 10 DEG and 200 DEG C. The acylcyanides (I) can be used as intermediates in the synthesis of known herbicides.

发明人：KUBO TAKASHI; MACHIDA MASAYUKI; FUJIOKA TOMONORI; YAMAGUCHI Shigenari; KAWAI KIYOSHI
权利人:KUMIAI CHEMICAL INDUSTRY CO
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.
