Abstract

Abstract The 6-(levulinyloxymethyl)-3-methoxy-2-nitrobenzoyl (LMM o NBz) and 2- (levulinyloxymethyl)-5-methoxy-4-nitrobenzoyl (LMM p NBz) groups were developed as novel base-labile groups for 5′-hydroxy protection in solid-phase oligonucleotide synthesis. A comparative study of the utility of LMM o NBz, LMM p NBz, and 2- (levulinyloxymethyl)-5-nitrobenzoyl (LMNBz) groups is described.
