发明人：DOLAI SUKANTA; BHAT SHREEDHAR; TARAFDAR GOURAV
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:A process for synthesis of an organosilicon compound is provided herein. Also, novel organosilicon compounds prepared by the present process is provided herein. The process comprises the reaction of a halosilane with an organofunctional alkyl halide in the presence of a metal catalyst, a promoter, and an optional co-catalyst. The process provides an efficient synthetic route to produce organosilicon compounds. The process also allows synthesis of organosilicon compounds with a plurality of different functional groups.

摘要:The total synthesis of taxol employs a convergent synthetic plan. The synthetic plan may also be employed to produce a large number of taxol analogs. Taxol analogs having skeletal extensions are inaccessible by modification of the natural product but are readily produced by employing the convergent synthetic plan herein.

标题 :Conversion of 9-dihydro-13-acetylbaccatin III to baccatin III and 10-deacetyl baccatin III
发明人：KASITU GERTRUDE C; NOAH JAPHETH W
摘要:Novel methods and synthetic intermediates to prepare baccatin III and 10-deacetylbaccatin from readily available 9-dihydro-13-acetylbaccatin III are described. Selective protection and deprotection of the C-7 hydroxyl functionality provides an entry into facile synthesis of novel taxol intermediates, as well as, providing new methods for the preparation of paclitaxel and docetaxel in large scale. Selective oxidation of the C-9 hydroxyl without the need for protection of the C-7 hydroxyl is described.

权利人:SOUKUP MILAN; MILAN SOUKUP
摘要:The present invention relates to a novel manufacturing process and novel intermediates useful in the synthesis of pharmaceutically active compound such as Aliskiren. n The invention describes preparation of enantiomerically pure 8-aryloctanoic acid of formula I from a chiral compound of formula IV. Friedel-Crafts reaction of this compound of formula IV with a compound of formula III provides compound of formula II which is converted reductively in a few steps into the compound of formula V, a know intermediate in the synthesis of compound of formula I. According to the disclosed process, Aliskiren can be now prepared from commercial starting materials (Guajacol or 2-bromoanisole, cis- or trans-1,4-dichloro-2-butene and 4(S)-benzyl-3-isovaleroyl-oxazolidin-2-one) in less than 8 process steps.

摘要:Bioactive ABC taxoids accessible by convergent synthesis have an intact AB ring framework of taxol, including the C13 side chain, and an aromatic C ring which substitutes for the CD ring system found on native taxol. The aromatic C ring may be substituted or unsubstituted. MPT derivatives of ABC taxoids are also disclosed.
