专利号:US-8580949-B2 优先权日:2009-07-27 标题:Enzymatic synthesis of carba-NAD 发明人:DUEFEL HARTMUT; HEINDL DIETER; HORN CARINA; MEIER THOMAS; SCHMUCK RAINER 权利人:DUEFEL HARTMUT; HEINDL DIETER; HORN CARINA; MEIER THOMAS; SCHMUCK RAINER; ROCHE DIAGNOSTICS OPERATIONS 摘要:The disclosure concerns the enzymatic synthesis of stable analogues of nicotinamide adenine dinucleotide NAD/NADH and nicotinamide adenine dinucleotide phosphate NADP/NADPH, the so-called “carba-NADsâ€?, i.e. analogues of NAD/NADH or NADP/NADPH, respectively, comprising a carbacyclic sugar instead of ribose.
专利号:US-4360470-A 优先权日:1980-10-22 标题 :Process and intermediates for the synthesis of Vitamin D3 metabolites and chenodeoxycholic acid 发明人:BATCHO ANDREW D; USKOKOVIC MILAN R; WOVKULICH PETER M 权利人:HOFFMANN LA ROCHE 摘要:The present disclosure is directed to a process for the synthesis of chenodeoxychloic acid, 25-hydroxycholesterol and 1α,25-dihydroxycholesterol from 17-keto steroids. A cholic acid side chain is stereospecifically introduced by reaction of the appropriate 17-keto steroid with ethyltriphenylphosphonium halides to produce the 17-ethylidene derivative which is allowed to react with acrylic acid esters or propiolic acid esters followed by hydrogenation.
