Stereoselective Synthesis of β-4′-Hydroxymethyl-Deleted Nucleosides via CPA-Ph3PS Cooperative-Catalyzed Iodocyclization
β-4′-Hydroxymethyl-deleted nucleosides are a class of four-carbon-sugar isonucleosides that possess significant research value in medicinal chemistry and artificial genetic polymer science. Nevertheless, current synthetic methodologies are hampered by several drawbacks, including poor diastereoselectivity, considerable...
