Stereoselective synthesis of 4′-C-branched 2,′3′-didehydro-2′-dideoxy nucleosides based on SnCl4-promoted allylic rearrangement
摘要:
Based on SnCl4-promoted allylic rearrangement between a 3',4'-unsaturated uracil nucleoside and organosilicon reagents, stereoselective introduction of carbon functionalities to the 4'-position has been accomplished, disclosing a new entry for a series of 4'-C-branched nucleosides of biological interests.
