Abstract

The present invention provides nucleosides an exocyclic amine-protected nucleoside of the formula: A-B where A is a 5′-protected ribose, 5′-protected-2-deoxyribose, 5′-protected-3′-phosphoramidite ribose, or 5′-protected-3′-phosphoramidite-2-deoxyribose moiety; and B is a nucleobase having an exocyclic amine group that is protected with di-tert-butylisobutylsilyl (“BIBS”) protecting group. Use of BIBS protecting group provides an exocyclic amine-protected nucleoside that is stable to a wide variety of reaction conditions associated with oligonucleotide synthesis. The present invention also provides, oligonucleotides comprising the same, and methods for producing the same.
