| 20080269501 | Synthesis of Phosphono-Substituted Porphyrin Compounds for Attachment to Metal Oxide Surfaces - A method of making a phosphono-substituted dipyrromethane comprises reacting an aldehyde or acetal having at least one phosphono group substituted thereon with pyrrole to produce a phosphono-substituted dipyrromethane; and wherein the phosphono is selected from the group consisting of dialkyl phosphono, diaryl phosphono, and dialkylaryl phosphono. Additional methods, intermediates and products are also described. | 10-30-2008 |
| 20100145066 | PHOSPHONATE COMPOUNDS - Novel phosphonate compounds are disclosed embodying an aminophosphonate moiety and a selected reaction partner. These compounds offer beneficial alternatives, and additional possibilities, to extant phosphonates and are capable of delivering desirable benefits from an application standpoint and from a compatibility standpoint broadly. | 06-10-2010 |
| 20110263870 | NOVEL PYRROLE DERIVATIVES AND THEIR SYNTHESIS - The present invention relates to two novel pyrrole derivatives [3-Phenyl-4-(phenylcarbamoyl)-2-(4-fluorophenyl)-5-(1-methylethyl)-pyrrole-1-yl]methyl(diphenyl)phosphine oxide and Diethyl [3-Phenyl-4-(phenylcarbamoyl)-2-(4-fluorophenyl)-5-(1-methylethyl)-pyrrole-1-yl]methylphosphonate. These pyrrole derivatives can be used as intermediates for the synthesis of the anticholesterol drug atorvastatin. | 10-27-2011 |
| 20120142939 | PROCESS FOR THE PREPARATION OF FOSINOPRIL AND INTERMEDIATES THEREOF - The present invention relates to a process for the preparation of intermediates useful in the synthesis of [1[S(R)],2α,4β]-4-cyclohexyl-1-[[[2-methyl-1-oxypropoxy)propoxy](4-phenylbutyl phosphinyl]acetyl]L-proline, and the synthesis thereof, in particular as sodium salt (fosinopril sodium). | 06-07-2012 |
| 548414000 | Polycyclo ring system having the five-membered hetero ring as one of the cyclos | 4 |
| 20080249317 | Novel amorphous form of carvedilol phosphate and processes for the preparation thereof - A novel form of amorphous carvedilol phosphate which is particularly suitable for pharmaceutical applications, and processes for preparing said novel form. | 10-09-2008 |
| 20090111998 | PROCESS FOR THE PREPARATION OF CARVEDILOL DIHYDROGEN PHOSPHATE HEMIHYDRATE AND PHARMACEUTICAL COMPOSITIONS THEREOF - There is provided processes for preparing carvedilol dihydrogen phosphate hemihydrate, which processes include at least one of the steps of: (a) providing a solution of carvedilol in a mixture of organic solvent (s) and/or water; (b) adding a phosphonating agent to the reaction mixture of step (a); and (c) further processing to obtain carvedilol dihydrogen phosphate hemihydrate. There is also provided pharmaceutical compositions comprising carvedilol dihydrogen phosphate hemihydrate and processes for their preparation. | 04-30-2009 |
| 20110054188 | NEAR INFRARED FLUORESCENT IMAGING AGENT - A compound represented by general formula (I) below, or a pharmacologically acceptable salt thereof: | 03-03-2011 |
| 548415000 | Plural chalcogens bonded directly to ring carbons of the five-membered hetero ring | 1 |
| 20110224443 | PREPARATION OF FOSAMPRENAVIR CALCIUM - Process for preparation of fosamprenavir and its intermediate salts using novel phthalimide intermediates. | 09-15-2011 |
