标 题 :Approach for synthesis of catechins
发明人：DUGAR SUNDEEP; MAHAJAN DINESH; RAI KUMAR SANTOSH; TRIPATHI VINAYAK; PATIL ISHWAR RAKESH
权利人:SPHAERA PHARMA PRIVATE LTD
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.
