- 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
