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.
