effects of 3-amido-2,3-dideoxyfuranose glycals were exploited in a novel and highly stereoselective synthesisstrategy for a variety of biologically active 3‘-amino-2‘,3‘-dideoxy- and 3‘-amino-3‘-deoxy-β-nucleosides, including puromycin aminonucleoside. In addition, the mechanism of the molybdenum-catalyzed alkynolcycloisomerization reaction has been studied. Evidence is p...
