标题 :Preparation of 2-chloro-4-fluoro-5-nitrobenzoic acid
发明人：GRABARNICK MICHAEL; GALGE REVANAPPA VASANTRAO
权利人:ADAMA AGAN LTD
摘要:The present invention relates to a novel nitration process of 2- chloro-4- fluorobenzoic acid or alkyl 2-chloro-4- fluorobenzoate, using oleum and nitric acid, to obtain 2-chloro-4- fluoro-5- nitrobenzoic acid or alkyl 2-chloro-4-f luoro-5-nitrobenzoates; purifying the crude reaction product; and recovering 2-chloro-4- fluoro- 5-nitrobenzoic acid or alkyl 2-chloro-4- fluoro-5- nitrobenzoates in an essentially pure form, which can be used in the synthesis of the herbicide saflufenacil.

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.
