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.

proposed a hybrid strategy by incorporating pharmacophores that bind to the acetylated lysine binding pocket of BET proteins with a typical kinase hinge binder to generate novel polypharmacological inhibitors of BET and kinases. Through elaborating the core structure of 6-(pyrimidin-2-ylamino)-3,4-dihydroquinoxalin-2(1H)-one, we demonstrated that this rational design can produce high potent inhibitors of CDK9
