  Liquid-Phase RNA Synthesis by Using Alkyl-Chain-Soluble Support

  摘要：

  AbstractRecent 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.
