Structure−Activity Relationships of 1-(2-Deoxy-2-fluoro-β- l -arabino- furanosyl)pyrimidine Nucleosides as Anti-Hepatitis B Virus Agents

Hongbum Kim, Chunguang Wang, Ju Sheng Lin, Tianwei Ma, Jinfa Du, M. Gary Newton, Chung K. Chu, Yung Chi Cheng, Kirupa Shanmuganathan, Yong Lian Zhu, S. Balakrishna Pai
Journal of Medicinal Chemistry | 1996 | 10.1021/jm960098l

Since 2‘-fluoro-5-methyl-β-l-arabinofuranosyluracil (l-FMAU) has been shown to be a potent anti-HBV agent in vitro, it was of interest to study the structure−activity relationships of related nucleosides. Thus, a series of...

Mo(CO) 3 (CN- t- Bu) 3 (MoBI 3 ), a New Efficient Catalyst for Regioselective Hydrostannations

Dagmar Schauss, Matthias Pohlman, Uli Kazmaier
Organic Letters | 1999 | 10.1021/ol990794q

Mo(CO) 3 (NC-t-Bu) 3 was found to be a suitable catalyst for the regioselective hydrostannation of several types of alkynes, giving preferentially rise to the α-stannylated products. These products are not available under radical reaction conditions or by...
