[作者:CSUK RENE; VASILEVA GALINA; BARTHEL ALEXANDER,期刊:Synthesis, 页码:2840-2842 , 文章类型: Article,,卷期:2012年44-18]
- Dihydromorphone was prepared from morphine in high yield, excellent purity, and low residual metal content. The key steps used palladium on porous glass and a modified Oppenauer oxidation, or Wilkinson's catalyst.
- D-Allal- and D-Galactal-Derived Vinyl N-Mesylaziridines: Regio- and Stereoselectivity in Addition Reactions of O-, C-, N-, and S-Nucleophiles
[作者:DI BUSSOLO VALERIA; FRAU ILEANA; PINESCHI MAURO; CROTTI PAOLO,期刊:Synthesis, 页码:2863-2871 , 文章类型: Article,,卷期:2012年44-18]
- The regioselectivity and stereoselectivity were examined of the addition reactions of O-, C-, N-and S-nucleophiles to D-allal- and D-galactal-derived N-mesylaziridines. The ratio of 1,4-regioselectivity (exclusive syn-1,...
- Synthesis of 2,4-Bis(aryloxy)-1,5-diarylpentane-1,5-diones by Base-Mediated Tandem Reaction
