专利号:WO-2009104605-A1 优先权日:2008-02-18 标 题 :Novel intermediate for synthesis of ascofranone having various physiological activities, and novel shortened total synthesis method for ascofranone using the same 发明人:SAIMOTO HIROYUKI; HAGA YASUSHI 权利人:ARIGEN PHARMACEUTICALS INC; SAIMOTO HIROYUKI; HAGA YASUSHI 摘要:In the synthesis of ascofranone, a compound represented by formula (III), (IV), (V) or (VII) or an optical isomer thereof is used as an intermediate for the synthesis. [In the formulae, R 1 and R 2 independently represent a hydrogen atom, a C 1-7 alkyl group, a phenoxyalkyl group having a halogen atom on a carbon atom in a benzene ring therein, or a phenyl group having a C 1-7 alkoxy group or a C 1-7 alkoxycarbonyl group on a carbon atom in a benzene ring therein; and X represents a halogen atom or a group R 5 SO 3 (wherein R 5 represents a C 1-7 alkyl group or a phenyl group having a C 1-7 alkyl group on a carbon atom in a benzene ring therein).] By using the compound, it becomes possible to reduce the number of steps required for the total synthesis of ascofranone to 7 or 8 from 12 which is a number of the steps required for the conventional ascofranone total synthesis processes.
专利号:US-7326805-B2 优先权日:2003-05-07 标题 :Method for the synthesis of 4-hydroxyisoleucine and the derivatives thereof 发明人:MIOSKOWSKI CHARLES; CATALA CEDRIC; WAGNER ALAIN 权利人:MIOSKOWSKI CHARLES; CATALA CEDRIC; WAGNER ALAIN 摘要:The invention relates to a method for the synthesis of two isomers, at function OH, alone or in mixtures, of amino acids α or the derivatives thereof, having general formula (B), wherein: linkage C—O of the 4-position carbon (represented by symbol) denotes one or other of isomers III or IV, or mixtures thereof. Moreover, R 1 and R 2 represent: a hydrogen atom; or either R 1 or R 2 represents a hydrogen atom and the other substituent is a radical R a , an acyl group —COR a , such as acetyl, or a functional group —COOR a , —SO 2 R a , —N (R a , R b ), R a and R b , which are identical or different, representing a C1-C12 linear or branched alkyl radical, optionally substituted, an aryl group with one or more aromatic rings and heterocycles, comprising between 5 and 8C, optionally substituted, or aralkyl, the alkyl substituent and the aryl group being as defined above; or R 1 and R 2 both represent a substituent as defined above. R 3 represents a hydrogen atom or R a and R 4 has the significance of R a . The invention is characterised in that it comprises: the isomerisation of a compound having formula (I), wherein R 1 , R 2 , R a , R 3 and R 4 are as defined above, such as to produce a compound having formula (II); and the reduction of the carbonyl function thereof which, depending on the catalytic system employed and the formula (I) compound used, produces one of the isomers having general formula (III) or (IV) or a mixture thereof having formula (B). The invention can be used for the synthesis of (2S, 3R, 4S)-4-hydroxyisoleucine.

专利号:US-7452994-B2 优先权日:2001-09-12 标 题 :Synthesis of enantiomerically pure amino-substituted fused bicyclic rings 发明人:MCEACHERN ERNEST J; BRIDGER GARY J; SKUPINSKA KRYSTYNA A; SKERLJ RENATO T; YANG WEN 权利人:ANORMED INC 摘要:This invention describes various processes for synthesis and resolution of racemic amino-substituted fused bicyclic ring systems. One process utilizes selective hydrogenation of an amino-substituted fused bicyclic aromatic ring system. An alternative process prepares the racemic amino-substituted fused bicyclic ring system via nitrosation. In addition, the present invention describes the enzymatic resolution of a racemic mixture to produce the (R)- and (S)-forms of amino-substituted fused bicyclic rings as well as a racemization process to recycle the unpreferred enantioner. Further provided by this invention is an asymmetric synthesis of the (R)- or (S)-enantiomer of primary amino-substituted fused bicyclic ring systems.
