专利号:US-4895996-A 优先权日:1988-10-17 标 题 :Synthesis of alkenes from enamines via hydroboration 发明人:GORALSKI CHRISTIAN T; SINGARAM BAKTHAN; BROWN HERBERT C 权利人:PURDUE RESEARCH FOUNDATION; DOW CHEMICAL CO 摘要:Alkenes are prepared by the hydroboration of enamines followed by an elimination reaction to form the alkene. This process has wide applicability and is useful for the stereospecific synthesis of [Z] isomers. It is preferred to use 9-borabicyclo[3.3.1 nonane as the hydroborating agent and to use methanol to catalyze the elimination reaction.
专利号:US-2005014954-A1 优先权日:2001-11-22 标 题:Pyrrole synthesis 发明人:OHRLEIN REINHOLD; BAISCH GABRIELE 摘要:The invention relates to a novel process for the preparation of N-substituted pyrroles, especially of formula (V), wherein the radicals are as defined in the description, by intermolecular aza-Wittig reaction starting from organic azides and 1,4-dioxo compounds. The invention relates also to novel iminophosphorane intermediates for this synthesis. The resulting pyrroles are useful, for example, in the organic synthesis of pharmaceuticals or other active substances and chemicals.

专利号:US-5229474-A 优先权日:1991-03-20 标题 :Synthesis of two-dimensional polymers by molecular recognition and chemical reaction among high molar mass monomers 发明人:STUPP SAMUEL I 权利人:UNIV ILLINOIS 摘要:A new variety of side chain liquid crystal polymers. The macromolecules of these materials are comb-shaped and differ from conventional side-chain liquid crystal polymers in that the comb's teeth are longer and semi flexible. The oligomeric side chains contain a long flexible spacer not only at their junction with the backbone but also in the center of the mesogen. Specific features of the systems include monosubstitution of enantiotopic protons in the central spacer by a cyano group and a long alkoxy tail at the terminus. An unusual property of these materials is a lower liquid crystal-isotropic transition temperature relative to that of their monomeric precursors.
专利号:US-8957260-B2 优先权日:2011-02-07 标题 :Process for the oxidation of mesitol 发明人:WEYRAUCH JAN PHILIPP; WEIS MARTINE; TELES JOAQUIM HENRIQUE; EBEL KLAUS; DEGLMANN PETER 权利人:WEIS MARTINE; TELES JOAQUIM HENRIQUE; EBEL KLAUS; DEGLMANN PETER; WEYRAUCH VIVIEN ELLINOR; WEYRAUCH GUNHILD; BASF SE 摘要:The invention relates to a process for the oxidation of mesitol with singlet oxygen, which is released from hydrogen peroxide, this release taking place in the presence of a bismuth compound as catalyst. In the process, 2,4,6-trimethylquinol is formed in high yield and selectivity as product, which can be used in further reactions for the synthesis of vitamins and in particular of vitamin A and vitamin E.
专利号:US-5502226-A 优先权日:1994-11-14 标 题:Process of preparing ω-hydroxy acids 发明人:CHO SUK H; DEFLORIO VICTOR 权利人:ARDEN ELIZABETH CO 摘要:A new synthesis of omega -hydroxy acids, which employs commercially available starting materials and lowers the cost of production. The process involves coupling a fatty acyl group by enamine chemistry, followed by a ring expansion and selective reduction of ketoacid.
