In 2010, LnIII imide chemistry was stirred by the successful isolation of the first scandiumIII terminal imide compound by Chen et al, exploiting a Lewis base-induced alkane elimination. We have developed organoaluminum-promoted syntheses of rare-earth metal imide complexes featuring even the large metal centers lanthanum and cerium.Get Price

2003-3-72,5,6-Trichloro-1--d-ribofuranosylbenzimidazole TCRB and certain analogues have shown significant activity against human cytomegalovirus. The metabolic instability of the glycosidic linkage in TCRB prompted us to synthesize the structurally similar imidazo1,2-apyridine erythrofuranosyl C-nucleosides. As an approach to the synthesis of polychlorinated imidazo1,2-apyridine C-3 ...Get Price
