标 题 :Process for the synthesis of vitamin k2
发明人：SHASTRI MAYANK; BAIKAR MRUNALI H; VORA PARIN K; BNS RAJU
权利人:SYNERGIA LIFE SCIENCES PVT LTD
摘要:The present disclosure relates to the synthesis of Vitamin K2 bearing varying prenyl side chains. The synthesis comprises the reaction of phenyl sulfone of tert-butyl dimethyl silyl (TBDMS) protected mono prenyl menadiol with prenyl halides bearing varying prenyl units in the presence of the phase transfer catalyst followed by reductive desulphonation to yield TBDMS ether of Vitamin K2. The TBDMS ether is then oxidized in the presence of chromium trioxide and periodic acid to yield the corresponding Vitamin K2.

标题 :Anti-viral multi-quinone compounds and regiospecific synthesis thereof
发明人：STAGLIANO KENNETH WILLIAM; EMADI ASHKAN
权利人:ILLINOIS TECHNOLOGY INST
摘要:This invention provides various biquinone and trimeric quinone derivatives. The invention also provides a method for synthesis of a multi-quinone compound including reacting a hydroxyquinone anion with a first quinone possessing a first directing group at a C-2 of the first quinone and a second directing group at a C-3 of the first quinone and obtaining a biquinone having one of the first and second directing groups at a C-3 of a first quinone monomer and a hydroxyl group at a C-3′ of a second quinone monomer. The biquinone can be further reacted to obtain various biquinone derivatives or with a second hydroxyquinone anion to obtain trimeric quinone derivatives, including trimeric naphthoquinone derivatives. The biquinones and trimeric quinones of this invention demonstrate antiviral activity and can be used to treat viral infections, particularly HIV infections.

标题 :C-alkylation of hydroquinone or monoethers thereof
发明人：DOUSSAIN CLAUDE; GUBELMANN MICHEL; TIREL PHILIPPE-JEAN
权利人:RHONE POULENC CHIMIE
摘要:The alkyl hydroquinones, e.g., methyl hydroquinone (a useful intermediate in the preparation of the monomer methyl hydroquinone diacetate, itself used for the synthesis of thermotropic polymers), are prepared by reacting (C-alkylating) hydroquinone or a monoether thereof with a lower alkanal, in the vapor phase, with a catalytically effective amount of at least one solid metal oxide.

标题 :Precursors for synthesis of triphendioxazine dyestuffs
发明人：SCHWAIGER GUENTHER; SPRINGER HARTMUT; HELMLING WALTER
权利人:HOECHST AG
摘要:Water-soluble triphendioxazine compounds which have fiber-reactive properties as dyestuffs, which afford deep and fast dyeings on fiber materials, such as wool and, in particular, cellulose, and which correspond to the formula (1) ##STR1## in which: n is the number 0 or 1; n Y is the vinyl group or an ethyl group containing, in β-position, a substituent which can be eliminated by means of an alkali; n Q 1 and Q 2 both represent a benzotriazole radical which can also be additionally substituted in the benzene nucleus by alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen, carboxy or sulfo; n B is --O--, --S--, --NH-- or --N(R')-- wherein R' is optionally substituted alkyl having 1 to 6 carbon atoms; n W 1 and W 2 both represent a divalent, optionally substituted aliphatic, cycloaliphatic, aliphatic-cycloaliphatic, araliphatic or aromatic-carbocyclic radical, it being possible for the aliphatic radicals to be interrupted by hetero groups --O--, --S--, --SO 2 --, --CO--, 1,4-piperidino, --NH-- and/or --N(R o )-- in which R o is optionally substituted alkyl having 1 to 6 carbon atoms or alkanoyl having 2 to 5 carbon atoms, and/or for aliphatic and aryl radicals to be attached to one another through such a hetero group; n R is hydrogen, alkyl having 1 to 6 carbon atoms, alkoxy having 1 to 6 carbon atoms, halogen, carboxyl or sulfo; n E is hydrogen, sulfo, carboxyl, a group --SO 2 --Y as defined above or an optionally substituted sulfonamide group; and n X 1 and X 2 are both hydrogen or halogen, cycloalkyl, alkoxy, aryloxy, aryl or another substituent; n and at least one carboxy, sulfo or sulfato group is present in the molecule (1), n and pre-products of those triphendioxazine compounds, of the general formula ##STR2## in which K is an amino or nitro group, Y' is β-hydroxyethyl or defined as for Y, W has one of the meanings of W 1 , and E' is hydrogen, sulfo, carboxy or a group of the formula --SO 2 --Y' defined above, or an optionally substituted sulfonamide group, and R, B and R* have the above meanings.

标 题:Synthesis of high quality normal alpha olefins
发明人：O'REAR DENNIS J; SCHINSKI WILLIAM L; ELOMARI SALEH; REYNOLDS RICHARD N; HERRON STEVEN J
摘要:Processes for converting linear hydrocarbon into normal alpha olefins (“NAOsâ€?). The process comprises a sequence of controlled dehydrogenation followed by ethenolysis. The process is especially applicable to upgrade linear hydrocarbons such as produced by Fischer-Tropsch type processes. A process for converting C 1 -C 3 alkanes into NAOs and an integrated process including hydrocracking are also disclosed.
