专利号:US-6540970-B1 优先权日:1999-11-18 标题:Method for the synthesis of molecular sieves 发明人:STROHMAIER KARL G; VAUGHAN DAVID E W 权利人:EXXON MOBIL CHEM PATENTS INC 摘要:The present invention provides a method for the synthesis of MeAPO molecular sieves which includes the following steps: providing a source of alumina, a source of phosphorus, water, and a template suitable for forming a MeAPO molecular sieve; providing a source of metal (Me) including metal particles, the metal particles measuring, in their largest dimension, equal to or less than five nanometers; providing a water soluble organic solvent capable of solubilizing the source of metal; forming a synthesis mixture from the source of alumina, the source of phosphorus, the water, the template, the source of metal, and the solvent; and forming a MeAPO molecular sieve from the synthesis mixture.
专利号:EP-0443532-B1 优先权日:1990-02-20 标题:Temporary minimal protection synthesis of LH-RH analogs 发明人:NESTOR JOHN J JR; MCCLURE NATALIE L 权利人:SYNTEX INC 摘要:A solid phase synthesis of LH-RH analogs in which the amino acids serine and histidine, if present, are side chain protected during the synthesis with groups labile to selected alpha -amino or deprotecting agents.
专利号:US-2024383940-A1 优先权日:2021-03-31 标题 :Synthesis of trinucleotide and tetranucleotide caps for mrna production 发明人:ENDO ATSUSHI 权利人:MODERNA TX INC 摘要:Provided herein are methods of making trinucleotides and tetranucleotides for use as 5′ mRNA caps. The methods utilize a novel “top-downâ€? strategy and provide for synthesis of oligonucleotides with higher yields and increased efficiency compared to traditional methods. A key step of the methods disclosed, herein can also be adapted to utilize a “one-potâ€? approach, resulting in an increase in the yield of the final oligonucleotide product.
专利号:US-5212288-A 优先权日:1990-02-20 标 题:Temporary minimal protection synthesis of serine-containing polypeptides 发明人:NESTOR JR JOHN J; MCCLURE NATALIE L; ARZENO HUMBERTO 权利人:SYNTEX INC 摘要:In a process for the solid phase synthesis of a polypeptide containing at least one serine residue, the improvement comprising temporarily protecting the side chain of the serine residue with a protecting group which is removed immediately following the addition of the serine to the peptide chain.
专利号:US-5859237-A 优先权日:1995-04-28 标 题:Process for the production of phthalocyanine pigment 发明人:NOGUCHI HIDETO; HAYASHI MIKIO; MOMOSE MASATOSHI 权利人:TOYO INK MFG CO 摘要:A process for the production of a phthalocyanine pigment having a clear color tone, a high tinting strength and a finely milled structure by an efficient and economical process, in which the pigmentation from a phthalocyanine crude can be carried out without removing an aromatic hydrocarbon solvent used in the synthesis of the phthalocyanine crude, the process comprising thes steps of n (a) reacting phthalic anhydride or its derivative, urea or its derivative and a catalyst in an organic solvent to synthesize a phthalocyanine crude, n (b) wet-milling a slurry of the synthesized phthalocyanine crude in the presence of a milling medium without removing the aromatic hydrocarbon solvent, and n (c) removing the organic solvent from the slurry of the milled product, purifying the milled product and drying the milled product with a spray type dryer.
专利号:US-6175009-B1 优先权日:1999-11-18 标题:Process for the preparation of quinazolinones 发明人:CONFALONE PASQUALE NICHOLAS; MAGNUS NICHOLAS ANDREW; STORACE LOUIS 权利人:DU PONT PHARM CO 摘要:The present invention relates generally to an asymmetric synthesis of 4,4-disubstituted-3,4-dihydro-2(1H)-quinazolinones, and intermediates thereof. The target compounds are useful for the treatment of human immunodeficiency virus (HIV) as an inhibitor of reverse transcriptase.
