Notes: Installs an amine at the 5'-terminus of oligonucleotides enabling fluorous affinity purification.1 Employs the fluorous monomethoxytrityl (FMMT) group rather than an MMT group, providing greater discrimination of full-length oligonucleotides over failure sequences.
For applications requiring the purification of 5'-amine-modified oligonucleotides, trityl-on purification is an option, typically involving a monomethoxytrityl (MMT) group. In cases where the separation of the trityl-on oligonucleotides from failure sequences and other non-trityl-bearing materials is more difficult, FMMT-5'-Amino-modifier-C6 CEP (FL 1500) is a useful option. It employs a fluorous version of the MMT group, i.e., a fluorous monomethoxytrityl (FMMT) group. This phosphoramidite behaves similarly to the MMT versions during synthesis, but the final FMMT-bearing oligonucleotide is more strongly retained on fluorous adsorbents or reversed-phase adsorbents, providing greater selectivity than observed for MMT-bearing oligos.
