| 20080262234 | Process for Preparing N, N-Substituted Carbamoyl Halides - The present invention relates to a new and useful process for preparing N,N-substituted carbamoyl halides from secondary amines, carbon dioxide, trialkylsilyl chloride and a halogenating agent. | 10-23-2008 |
| 20090198065 | RESIST POLYMER, RESIST COMPOSITION, PROCESS FOR PATTERN FORMATION, AND STARTING COMPOUNDS FOR PRODUCTION OF THE RESIST POLYMER - To provide a resist polymer comprising, as a structural unit, an acid-decomposable unit having a structure represented by formula (1) or (2) which exhibits a small line edge roughness and produces little defects in DUV excimer laser lithography or the like. | 08-06-2009 |
| 20100010228 | PROCESS FOR THE ASYMMETRIC REDUCTION OF 3-BENZOYLPIPERIDINES - Disclosed is a process for the asymmetric preparation of a phenyl(3-piperidinyl)methanol represented by Formula (I): | 01-14-2010 |
| 20120123128 | PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE NIPECOTAMIDE - Optically active nipecotamide can be produced by a method for producing optically active nipecotamide comprising: a step of reacting nipecotamide with optically active lactic acid to prepare a mixture of diastereomer salts and then allowing one diastereomer salt in the mixture of the diastereomer salts to precipitate; a step of collecting the precipitated diastereomer salt; and, a step of treating the collected diastereomer salt with a base to cause optically active nipecotamide to release. | 05-17-2012 |
| 20120264941 | METHOD FOR PREPARING DITHIOCARBAMATES IN PARTICULAR FROM POLYOLS OF THE GLYCEROL TYPE - The present invention concerns a method for the synthesis of glycerol dithiocarbamates or bis-dithiocarbamates (GDTCs) in which a reaction medium comprising (1) a carbonate selected from diethyl carbonate, dimethyl carbonate and ethylene or propylene carbonate associated with a glycerol type polyol in the presence of a basic catalyst or (2) a cyclic carbonate comprising five ring members, in a solvent medium, is supplemented with a primary or secondary amine in the presence of carbon disulphide, and the GDTC formed is recovered. In particular, a glycerol type polyol is brought into the presence of diethyl carbonate in the presence of a catalyst, then a primary or secondary amine is added to the reaction medium in the presence of carbon disulphide, and the GDTC formed is recovered. The invention can be used for one-step synthesis of glycerol dithiocarbamates directly from glycerol as the starting material and solvent. This method involves glycerol, diethyl carbonate, carbon disulphide (CS | 10-18-2012 |
| 20130165658 | PROCESS FOR THE PREPARATION OF IODIDES - This invention is directed to a process for the preparation of high yield alkyl or aryl iodide from its corresponding carboxylic acid using N-iodo amides. | 06-27-2013 |
| 20140088310 | PROCESS INTERMEDIATES AND METHODS FOR THE PREPARATION OF PROCESS INTERMEDIATES FOR THE SYNTHESIS OF ARGATROBAN MONOHYDRATE - Methods are provided for the synthesis of key intermediates for the synthesis of Argatroban monohydrate, ethyl (2R,4R)-1-[(2S)-2-amino-5-[[imino(nitroamino)methyl]amino]-1-oxopentyl]-4-methylpiperidine-2-carboxylate compounded with HCl. Such intermediates are also provided. | 03-27-2014 |
| 20140343289 | PROCESS FOR PRODUCING SOLID AMINO ACID - The problem to be solved by the present invention is to ea lily and efficiently produce an amino acid having 2 to 7 carbon atoms as a high-purity solid without complicated operation, which is useful as a synthetic intermediate for medicines or agrochemicals. | 11-20-2014 |
| 20150094474 | AGRICULTURAL CHEMICALS - The present invention relates to derivatives of compounds which are known to be of use in the field of agriculture. These derivatives are differentiated from the parent active compound by virtue of being redox derivatives of the active compound. This means that one or more of the functional groups in the active compound has been converted to another group in one or more changes one or more of which may be considered to represent a change of oxidation state relative to the groups in the original compound. We refer to these compounds generally as redox derivatives. The compounds are of use as insecticides, herbicides and insect repellents. | 04-02-2015 |
