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:The present invention describes the synthesis of six novel derivatives of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF), utilising the recently developed reaction of 1,8-diketones with Lawesson's reagent. These new BEDT-TTF derivatives (1)-(6) have potential to delocalise the positive charges formed during change-transfer salts to the peripheral. In addition to their positive charge delocalisation feature, the compounds (1)-(3) have the potential of being introduced hydrogen bonding groups and the compound (4)-(6) already have hydrogen bonding hydroxyl groups. All the new BEDT-TTF (7) derivatives described in this invention have shown comparative CV measurements with the BEDT-TTF. Each of these bis(ethylenedithio)tetrathiafulvalene derivatives of the present invention has a unique and novel structure which can not be found in the prior art and is useful for the development of new organic charge-transfer complexes.
