The present invention discloses novel compounds which have HCV protease inhibitory activity as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such compounds as well as methods of using them to treat disorders associated with the HCV protease.
A binary catalyst system of [RuCl2(η6-arene)]2 and a protic aminothiol (SN) ligand has been found to promote hydrogen transfer between alcohols and carbonyl compounds. The chiral catalyst system with the pipecolinol-derived chiral SN ligand displays excellent stereoselectivity in the asymmetric transfer hydrogenation of aromatic ketones using HCO2H-Et3N. Novel unsymmetrical bis(thiolate)-bridged binuclear complex, which is relevant to the generation of catalytically active species, has been synthesized and structurally characterized.
发现了一种二元催化剂体系,由 [RuCl2(η6-芳烃)]2 和质子性氨基硫醇 (SN) 配体组成,能够促进醇和羰基化合物之间的氢转移。使用 HCO2H-Et3N 的具有哌啶醇衍生的手性 SN 配体的二元催化剂体系在对芳香酮的不对称转移氢化中显示出优异的立体选择性。合成并结构表征了一种新型非对称双硫醇盐桥连的双核配合物,该配合物与催化活性物种的生成相关。
