专利号:US-9714205-B2 优先权日:2014-04-04 标题 :Process for direct synthesis of (meth)acrolein from ethers and/or acetals 发明人:DUBOIS JEAN-LUC 权利人:ARKEMA FRANCE 摘要:The subject matter of the present invention is a process for direct synthesis of (meth)acrolein from a reactive mixture comprising at least one compound chosen from ethers, acetals or hemiacetals derived from linear alcohols comprising from 1 to 3 carbon atoms. Examples of compounds are dimethyl ether, diethyl ether, methyl ethyl ether, dimethoxymethane, diethoxymethane, dipropoxymethane, 1,1-dimethoxyethane or 1,1-diethoxyethane. The process of the invention comprises two successive phases: oxidation then aldol condensation, which can be carried out in the presence of a solid oxidation catalyst chosen from molybdenum-based catalysts and optionally of an aldol condensation catalyst. These two phases are carried out in a reaction system comprising a single reactor or optionally two reactors in cascade.
专利号:US-9982005-B2 优先权日:2013-04-04 标 题 :Macrolides and methods of their preparation and use 发明人:MYERS ANDREW G; SEIPLE IAN BASS; ZHANG ZIYANG 权利人:HARVARD COLLEGE 摘要:Provided herein are methods of preparing macrolides by the coupling of an eastern and western half, followed by macrocyclization, to provide macrolides, including both known and novel macrolides. Intermediates in the synthesis of macrolides including the eastern and western halves are also provided. Pharmaceutical compositions and methods of treating infectious diseases and inflammatory conditions using the inventive macrolides are also provided. A general diastereoselective aldol methodology used in the synthesis of the western half is further provided.
专利号:US-6777562-B1 优先权日:2003-02-19 标 题:Preparation of a trans-calanolide ketone intermediate and chiral separation of calanolide alcohols to give racemic calanolide A 发明人:DAUGS EDWARD D 权利人:DOW GLOBAL TECHNOLOGIES INC 摘要:The method of the invention comprises a process for synthesizing a trans-calanolide A ketone intermediate used in the synthesis of racemic trans-calanolide A. The invention further comprises a method for removing a racemic calanolide B diastereomer from a mixture of calanolide A and calanolide B diastereomers formed in the last step of the synthesis of calanolide A by crystallization.
专利号:WO-2024256370-A1 优先权日:2023-06-13 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.

专利号:US-11919928-B2 优先权日:2016-03-16 标题 :Method for producing dihydrotentoxin 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.
