Abstract

Abstract: Amidines have been investigated for protection of deoxyadenosine, deoxycytidine, 5-methyldeoxycytidine, cytidine, and deoxyguanosine. These amidine-protected nucleosides and their 5'-bis (p-anisylphenyI) methyl derivatives were prepared in high yield (79-100%) by simple one-flask procedures, converted to their respective phosphoramidites [3'-O-((diiso-propylamino) methoxyphosphino)] with bis (diisopropylamino) ...
