摘要:The invention relates to commercially viable process for the synthesis of key intermediates for the preparation of statins, in particular Rosuvastatin and Pitavastatin or respective pharmaceutically acceptable salts thereof. A new simple and short synthetic route for key intermediates is presented which benefits from the use of cheap and readily available starting materials, by which the conventionally most frequently used DIBAL-H as reducing agent can be avoided.

权利人:UNIV KENTUCKY RES FOUND
摘要:The present disclosure relates to the synthesis of non-natural analogs of S-adenosyl-L-methionine (SAM) and/or of Se-adenosyl-L-methionine (SeAM) by reacting a methionine analog and adenosine triphosphate (ATP) in the presence of at least one methionine adenosyltransferase (MAT), and to use thereof with downstream SAM and/or SeAM utilizing enzymes. The non-natural analogs of SAM and/or SeAM have the general formula: n nwhere X is S or Se, and R 1 is an alkyl group.

摘要:A process for synthesis of enatiomerically pure or enatiomerically enriched or racemic mixture of (+ and/or −) epicatechin and its intermediates, comprising the steps of: (i) obtaining penta-protected quercetin; (ii) reducing the penta-protected quercetin obtained from step (i); (iii) optionally deprotecting the compound of step (ii); (iv) reducing the compound obtained from step (ii) or step (iii) in the presence of a chiral/achiral reducing agent to obtain a chiral intermediate; (v) deprotecting and/or hydrogenation of the chiral intermediate obtained from step (iv) to obtain (−)-epicatechin; (vi) optionally simultaneously deprotecting and by drogenation of the compound obtained from step (ii) to obtain racemic epicatechin.

标 题 :Methods utilizing aryl thioimines in synthesis of erythromycin derivatives
发明人：LUKIN KIRILL A
权利人:ABBOTT LAB
摘要:An efficient deoximation technique for use in synthesis of erythromycin derivatives, involving aryl thioimine intermediates is disclosed. The aryl thioimine intermediates can be utilized in a method for protecting a ketone of a ketone-containing erythromycin derivative as a thioimine; a method for deoximating an oxime-containing erythromycin derivative, or a method for preparing a 6-O-alkyl erythromycin derivative. Presently preferred erythromycin derivatives have a C-9 oxime or a C-9 ketone.

权利人:UNIV DURHAM
摘要:The present invention provides a method of making an enantiomerically enriched tertiary or quaternary ammonium salt, and the use of a non-racemic chiral compound in the synthesis of an enantiomerically enriched tertiary or quaternary ammonium salt. The control of nitrogen-based chirality, achieved via the method of the invention, is useful where a specific tertiary or quaternary ammonium enantiomer is preferred over the other enantiomer, for example where a specific tertiary or quaternary ammonium enantiomer is more effective than the other enantiomer in treating a specific medical condition.

标 题:Synthesis of 13-alkyl-gon-4-ones
发明人：HUGHES GORDON ALAN; SMITH HERCHEL
权利人:SMITH HERCHEL
摘要:The preparation of 13-methylgon-4-enes and novel 13-polycarbonalkylgon-4-enes by a new total synthesis is described. 13-Alkylgon-4-enes having progestational, anabolic and androgenic activities are prepared by forming a tetracylic gonane structure unsaturated in the 1,3,5(10),9(11) and 14-positions, selectively reducing in the B- and C-rings, and converting the aromatic A-ring compounds so-produced to gon-4-enes by Birch reduction and hydrolysis.
