| 20080312466 | Synthesis and intermediates - The invention relates to novel synthesis methods for the preparation of statin derivatives, which methods proceed by way of a key intermediate of formula I | 12-18-2008 |
| 20090018354 | PREPARATION OF ALPHA-HYDROXY AND ALPHA-AMINO KETONES - A process for the preparation of an 1,1-disubstituted oxirane is disclosed, wherein an organic sulphide is reacted in a polar solvent with an educt containing a leaving group attached to a primary or secondary carbon atom, and/or the sulfonium salt formed in this way is reacted with a ketone in presence of a base and a polar solvent. Oxiranes of the type obtained may be further converted into the corresponding α-hydroxyketone or α-aminoketone, either in one step by subjecting to aerobic oxidation in the presence of a transition metal catalyst, or in two steps by hydrolyzation in the presence of an aqueous acid to the corresponding dialcohol and subsequent selective oxidation. Further described are some novel epoxide intermediates. The α-hydroxyketones and α-aminoketones thus obtainable are useful inter alga as photoinitiators. | 01-15-2009 |
| 20090044345 | Use of Metal Complex Compounds as Oxidation Catalysts - The present invention relates to the use, as oxidation catalysts, of metal complex compounds having tetradentate ligands of formula (2) wherein all substitutents have the meanings as defined in Claim | 02-19-2009 |
| 20090106915 | Coloring keratin fibers with metal complexes - The present invention concerns coloring keratin fibers, especially human hair, with colored metal complexes. | 04-30-2009 |
| 20110021407 | USE OF METAL COMPLEX COMPOUNDS AS OXIDATION CATALYSTS - The present invention relates to the use of metal complex compounds having hydrazide ligands as oxidation catalysts. Further aspects of the invention are formulations comprising such metal complex compounds, novel metal complex compounds and novel ligands. The metal complex compounds are used especially for enhancing the action of peroxides, for example in the treatment of textile material, without at the same time causing any appreciable damage to fibres and dyeings. There is also no appreciable damage to fibres and dyeings if these metal complexes are used in combination with an enzyme or a mixture of enzymes. | 01-27-2011 |
| 20110046411 | PROCESS FOR THE PREPARATION OF INTERMEDIATES USEFUL IN THE SYNTHESIS OF STATIN DERIVATIVES - The invention relates to novel synthesis methods for the preparation of statin derivatives, which methods proceed by way of a key intermediate of formula I | 02-24-2011 |
