Stereocontrolled synthesis of pyrimidine 2′,3′-dideoxy-β-nucleosides by intramolecular glycosylation
摘要:
beta-2',3'-Dideoxynucleosides and their 3'-azido and 3'-fluoro substituted derivatives were synthesized in a stereocontrolled manner by th dimethyl(methylthio)sulfonium tetrafluoroborate promoted intramolecular glycosylation of phenyl 2,3-dideoxy-5-O-(2-pyrimidyl)-1-thioglycosides followed by hydrolysis or ammonolysis.
