Synthesis of new type of dendritic molecule and its columnar self-assembly having a potential as molecular cavity

In this study, we synthesized the first generation aromatic polyamide dendron having one trioxyethylene chain at the top of the dendron and six octadecyl chains at the other terminals. This material forms two types of crystals, K1 and K2/

SYNTHESIS OF OLIGONUCLEOTIDES AND RELATED COMPOUNDS

Methods of synthesizing oligonucleotides via new intermediates on a cleavable support having an azidomethyl moiety are disclosed. The method comprises multiple reaction cycles, each of which comprises sequential coupling a nucleoside or oligonucleotide su

Control the self-assembly of fluorenone-based polycatenars by tuning chain length

Using Suzuki coupling reactions as key steps, a series of fluorenone-based polycatenars, consisting of a central 2,7-diphenyl-9-fluorenone core connected with the 3,4,5-trialkoxybenzoate unit via –COO- linkage at each side have been synthesized. Upon elon

METHOD FOR LIQUID-PHASE SYNTHESIS OF NUCLEIC ACID

In this method, an oligonucleotide is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R1, Y, Base, Z, Ar, R2, R3 and n are each as defined in Claim 1]. The

Liquid-phase RNA synthesis by using alkyl-chain-soluble support

Recent progress in the RNA therapeutics has increased demand for the synthesis of large quantities of oligoribonucleotides. The assembly of RNA oligomers relies mainly on solid-phase approaches. These allow rapid product purification and the ability to drive a target reaction to completion through the use of excess reagents. Despite the known advantages of solid-phase synthesis, some issues in the process remain to be addressed, such as low and limited scale, reagent accessibility, and the use of a very large excess of reagents. Herein, we report a highly efficient and practical method of liquid-phase synthesis of RNA oligomers by using alkyl-chain-soluble support. We demonstrate the utility of the liquid-phase method through 21-mer RNA synthesis on a gram scale. The assembly of RNA oligomers relies principally on solid-phase approaches, although some alternative methods have been developed to date. A highly efficient and practical method of liquid-phase synthesis for RNA oligomers by using an alkyl-chain-type soluble support is reported. The utility of the liquid-phase method through 21-mer RNA synthesis on a gram scale is described (see scheme). Copyright

Effect of central linkages on mesophase behavior of imidazolium-based rod-like ionic liquid crystals

Two series of phenylbenzylether and benzanilide based rod-like imidazolium bromides and their nonionic precursors, the 1-phenyl-1H-imidazoles have been synthesized and the influence of the number and length of the alkyl chain(s) and the structure of the linking group in the aromatic core (-CH2O-, -COO-, -CONH-) on their mesophase self-assembly in ionic liquid crystalline phases were studied by POM, DSC and XRD. Upon decreasing the length of the N-terminal chain or by enlarging the number and length of the C-terminal chains, the sequence smectic (SmA)-hexagonal columnar (Colhex)-micellar cubic (CubI/Pm3n) was found for the ether based imidazolium salts; while only SmA and Colhex phases were observed for the related amides. The influence of the polarity of the central linkages, namely -CH 2O- and -CONH-, on the mesophase structure and stability is discussed and compared with related -COO- connected ILC.

Columnar liquid-crystalline phase from a series of symmetrical bent diphenylamine derivatives: Synthesis and characterization

A series of symmetrical bent-shaped materials with six alkoxy chains at the terminal position has been designed and synthesized. All except one exhibit columnar mesophase behavior. The mesomorphic properties of the compounds have been studied with the help of polaralizing optical microscopy (POM) and differential scanning colorimetry (DSC) experiments.
