&ggr;-Hydroxy-2-(fluoroalkylaminocarbonyl)-1-piperazinepentanamide compounds are inhibitors of HIV protease and inhibitors of HIV replication. These compounds are useful in the prevention or treatment of infection by HV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described. These compounds are effective against HIV viral mutants which are resistant to HIV protease inhibitors currently used for treating AIDS and HIV infection.

A β‐diketimine ligand with vinylidene substitution at γ‐carbon, CH2C(CH3CNAr)2 (Ar = 2,6‐diisopropylphenyl) (L2), was synthesized by treating β‐diketimine H2C(CH3CNAr)2 with n‐BuLi followed by paraformaldehyde. L2 formed the homobimetallic ether‐bridged β‐diketiminatecomplex [O(CH2‐β‐diketiminate)Pd(OAc)}2] (1) with (PdOAc)2. It also gave complexes [L2PdCl2] (2) and [L2NiBr2] (3) when treated with

bearing unsymmetrical cyano- and ester-functionalized NHC ligands as potential IR probes were studied in detail. Direct reaction of Pd(OAc)2 with functionalized imidazolium salts afforded either bis(carbene) (3a, c) or monocarbene complexes (5, 6) with a N-coordinated imidazole co-ligand. The latter were exclusively obtained with N-ethylene substituted salts, which were found to undergo N–C cleavage reaction

these results, two new propylene-bridged hetero-dicarbene complexes (7 and 8) were designed containing a mixed benzimidazole/imidazole-derived NHC-donor set. Notably, both complexes outperformed their homo-dicarbene analogues, which may be due to the electronic asymmetry induced by hetero-dicarbene ligands. The molecular structures of complex 6 and 8 are also presented.
一系列的钯(II)络合物(1 - 6)轴承顺-chelating同源dicarbene配体具有不同的烷基桥(C1-C3)和ñ -杂环骨架(咪唑和苯并咪唑)已经通过将Pd(OAc)的反应合成的2在溴化二甲基亚砜中具有各自的重氮溴化物(A 2HBr- F 2HBr)。一项在Mizoroki-Heck反应中使用芳基氯化物的比较催化研究表明,亚甲基和丙烯桥联的二苯并咪唑啉-2-亚烷基比其咪唑衍生的类似物优越。基于这些结果,发现了两个新的丙烯桥杂二碳烯配合物(7和8)被设计为含有混合的苯并咪唑/咪唑衍生的NHC供体。值得注意的是,这两种配合物的性能均优于均二碳烯类似物,这可能是由于异二碳烯配体引起的电子不对称性。还给出了配合物6和8的分子结构。
