标 题:Method for liquid-phase synthesis of nucleic acid
发明人：NONOGAWA MITSURU; NAGATA TOSHIAKI; SAITO HIDEKI; YASUMA TSUNEO
权利人:TAKEDA PHARMACEUTICALS CO
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.

摘要:A process of hydrocyanation of diolefins such as butadiene is carried out in the presence of a catalytic system comprising a transition metal and mono- and pluri-dentate organophosphorus ligands. The reaction medium containing branched nitrites subsequently is isomerized in the absence of hydrogen cyanide.

摘要:The present invention relates to a process for the industrial preparation of a diamine starting from a corresponding alkenyl nitrile comprising at least one C—C double bond, which comprises the stepsn (a) reaction of the alkenyl nitrile with a corresponding monoamine in a first reactor so that the monoamine adds exothermically onto the at least one double bond to form an aminoalkyl nitrile, with the monoamine and water being charged initially and the alkenyl nitrile being fed in; (b) evaporation of unreacted alkenyl nitrile and monoamine to increase the concentration of the aminoalkyl nitrile product in the bottoms of the first reactor; (c) transfer of the aminoalkyl nitrile bottom product from step (b) to a second reactor; (d) batchwise catalytic hydrogenation of the aminoalkyl nitrile transferred in step (c) to the diamine in the second reactor, with each batch being obtained by initially charging a catalyst suitable for the hydrogenation of nitriles to amines and also water, the desired diamine and a base, introducing hydrogen into the second reactor and feeding in the aminoalkyl nitrile transferred in step (c); and (e) isolation of the diamine and, if appropriate, repetition of the steps (a) to (e). nn The invention further relates to an apparatus for preparing these diamines and the use of the apparatuses. A preferred diamine is 3-dimethylaminopropylamine (DMAPA).

摘要:Alcohols may be synthesized by reacting an olefinic compound, carbon monoxide and hydrogen in the presence of a Group VIII organometallic complex catalyst at reaction conditions which include a temperature in the range of from about 50° to about 250° C. and a pressure in the range of from about 10 to about 300 atmospheres. In addition, the reaction is also effected in the presence of a promoter compound comprising a nitrile.
