J. Hovinen et al., Ethyl[2-deoxy-5-O-(4,4 '-dimethoxytrityl)-alpha-and beta-D-erythro-pentofuranosyl] acetates as versatile intermediates in nucleic acid chemistry, NUCLEOS NUC, 18(6-7), 1999, pp. 1263-1264
The title compounds (1a,b) were synthesized in three steps from 2-deoxy-D-r
ibose, and used in the preparation of oligonucleotide conjugates, branched
oligonucleotides as well as homo-N-nucleosides.
