| 20090124803 | PROCESS FOR PREPARATION OF ROSUVASTATIN - The invention relates to commercially viable process for the preparation of Rosuvastatin by an early introduction of the correct absolute stereochemistry at C-5 (S) of Rosuvastatin side chain followed by regioselective chain extension using novel side chain building blocks. It is yet another object of the invention is to provide novel intermediates that may be used for the preparation of Rosuvastatin. Formula (I). | 05-14-2009 |
| 20100298567 | NITRATION OF ACTIVATED AROMATICS IN MICROREACTORS - The invention relates to the nitration of aromatic or heteroaromatic compounds, wherein an activated aromatic or heteroaromatic compound and a nitration agent, optionally in the presence of a solvent, are mixed intensely in a microreactor, and wherein the proportion of the nitration agent to the activated aromatic or heteroaromatic compound, the concentration of nitration agent in the reaction mixture, and the temperature are selected at levels such high that the nitration begins autocatalytically, and wherein the nitration product is obtained after leaving the microreactor and, optionally after an after-reaction time outside the microreactor. | 11-25-2010 |
