标题:一类膦功能化聚醚吡啶盐离子液体及其在烯 烃氢甲酰化反应中的应用
摘要:本发明涉及一类膦功能化的聚醚吡啶盐离子液体,以及一种基于膦功能化聚醚吡啶盐离子液体的烯烃两相氢甲酰化的方法,该方法采用了一种两相催化体系,该催化体系由膦功能化的聚醚吡啶盐离子液体,铑催化剂以及反应底物烯烃和反应产物醛组成,在一定的反应温度和合成气压力下进行液/液两相氢甲酰化反应,膦功能化的聚醚吡啶盐离子液体既是膦配体,同时又充当铑催化剂的载体,体系中无需再另外引入其它离子液体,反应结束后通过简单的液/液两相分离实现铑催化剂的分离和循环,该催化体系具有较高的催化活性,铑催化剂可循环使用多次,催化活性和选择性没有明显的下降.

标题:Method for the synthesis of bis-tetrahydrofuranyl annonaceous acetogenins
发明人：HOYE THOMAS R; TAN LUSHI
权利人:UNIVERISTY OF MINNESOTA
摘要:A method for the synthesis of bis-tetrahydrofranyl Annonaceous acetogenins, including the natural products and analogs thereof, is provided which proceeds by the Pd-mediated coupling of a bis-tetrahydrofuranyl-subunit comprising a terminal alkyne, with a (C4)-hydroxybutenolide subunit comprising a terminal vinyl iodide, followed by selective reduction of the resulting enyne.

摘要:A method for the synthesis of cyclic acetals comprises reacting at least one carbonyl-function compound selected from aldehydes, ketones, and/or linear acetals, on a polyol in a concentrated aqueous solution exceeding 20 wt % in a reactor containing an acidic catalyst. The carbonyl-function compound is selected so that the cyclic acetal obtained has a water solubility lower than 20000 mg/kg. During the catalytic reaction for the cyclic acetal synthesis, at least one portion of the organic phase containing the cyclic acetal is separated. The acidic catalysis is either homogeneous when using a water-soluble strong acid, or heterogeneous when using a solid acid such as a resin, a zeolite, or any appropriately acidified solid. The extractive reaction method can be used for obtaining high conversions and selectivity.

摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , Q, Base, r and r′ are each as defined in claim 1 ] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R 1 , Y, Base, Z, Ar, R 2 , R 3 and n are each as defined in claim 1 ]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.
