摘要

Nucleoside phosphoramidites bearing a fluorous dimethoxytrityl (FDMT) group were used to synthesize fluorous-tagged oligonucleotides, which were subjected to solid-phase extraction using a pH-stable fluorinated adsorbent. On-column detritylation afforded the purified oligonucleotides. The fluorous affinity purification method offers one-pass loading without ammonia removal, high selectivity for the removal of failure sequences, high recoveries ( ...
