Abstract

Abstract New base protecting groups are proposed in place of benzoyl and isobutyryl groups. They are phenoxy acetyl for adenine and guanine and isobutyryl for cytosine. They are cleaved in aqueous ammonia in a shorter time at lower temperature. These easily removable groups are useful in the synthesis of modified oligonucleotides, containing fragile bases.
