SCHUTZGRUPPEN UND IHRE VERWENDUNG IN EINEM VERFAHREN ZUR OLIGONUKLEOTID-SYNTHESE

摘要

Phosphoramidite oligonucleotide synthesis is facilitated by the use of fluoride-labile 5' silyl protecting groups. RNA synthesis is improved by the use of 2' orthoester protecting groups. Reactions are conducted on a solid phase support, and acidic deprotection conditions are avoided, as is the necessity of oxidizing the phosphite linkage between each coupling reaction.
