  Ligand-Mediated Highly Effective and Selective C−N Coupling for Synthesizing BioactiveN-Aryltriazole Acyclonucleosides

  摘要：

  N-aryltriazole nucleosides are new chemical entities with potential biological activity. The two phosphor ligands, Synphos and Xantphos, had a selective and effective impact on Pd-catalyzed C-N coupling with the 5- and 3-bromotriazole acyclonucleoside isomers, affording the corresponding and otherwise difficult to achieve N-aryltriazole nucleosides with good to excellent yields. In addition, two of the synthesized nucleosides showed superior anticancer activity against drug-resistant pancreatic cancer, compared to the reference drug gemcitabine.

  Chiral, bidentate phosphine ligands (R,R-CHIRAPHOS, R-PROPHOS, S,S-BDPP, R,R-Me-DUPHOS, R,R-NORPHOS) react with trans-platinum acetylide complexes 1a and 1b, (Ph3P)2Pt(C≡CR)2 (R = TIPS, p-MeC6H4), via ligand exchange to generate chiral platinum acetylide complexes. The corresponding cis-platinum complexes are formed in all cases except for the reaction of 1b with S,S-BDPP, where the dimeric complex

Catalysts that exist as a single diastereomer, prepared with enantiomerically pure diphosphanes, catalyze the hydrogenation of prochiral ketones with moderate levels of enantioselectivity that are significantly improved relative to catalysts existing in several conformations
