A compound which is a thiazole derivative of Formula (I), or a pharmaceutically acceptable salt thereof,
wherein R1, R2, n, Z, L, Ring B, R4 and n are as herein defined. Such compounds are useful in the prevention and treatment of bacterial infection. In particular, the compounds are inhibitors of metallo-β-lactamase and are useful in combination with antibiotic agents such as carbapenems in the treatment of infection caused by bacteria that are resistant to treatment with antibiotic agents when administered alone.
hydrosilylation of terminal alkynes with HSiMe2Ph has been investigated with PhC≡CH, TolC≡CH, nBuC≡CH, Et3SiC≡CH, and (CPh2OH)C≡CH as substrates. The steric hindrance on the N-heterocyclic ligand and on the alkyne substrates affects conversion and selectivity: for the former the best results were achieved employing the less encumbered 3a catalyst with TolC≡CH, whereas by employing hindered alkynes such as Et3SiC≡CH
酰胺官能化的咪唑鎓盐[BocNHCH 2 CH 2 ImR ] X(R = Me,X = I,1a ; R =苄基,X = Br,1b ; R =三苯甲基,X = Cl,1c)带有越来越大的N-通过(2-咪唑-1-基-乙基)氨基甲酸叔丁酯的直接烷基化,高产率地制备烷基取代基。1c是结晶固体,其特征还在于X射线衍射。这些盐是合成铑(I)配合物[Rh(NBD)X(NHC)]的前体(NHC = 1-(2-NHBoc-乙基)-3-R-咪唑啉-2-亚基; X = Cl, R = Me(3a),R =苄基(3b),R =三苯甲基(3c); X = I,R = Me(4a))。所有的配合物都表现出绕金属碳烯键旋转受限的现象。然而,尽管为3a,b和4a计算的旋转势垒与实验值匹配,但出乎意料的是,对于3c而言,情况并非如此,因为3c的实验值等于化合物3b的实验值(58.6 kJ mol –1),并且相对于所计算的值较小(100
Synthesis, molecular structures and solution NMR studies of N-heterocyclic carbene–amine silver complexes
2-ylidene), a tetranuclear complex [Ag(NHC–NHBoc)2]2[Ag2I4], (5), and a polymericsilver “staircase” [(NHC–NHBoc)2–Ag4–I4]n, (6) composed of Ag4I4 clusters. The same reaction carried out with [3]I showed that a primary silver mono-NHC–NH2 carbene complex of the type [(NHC–NH2)AgI] (7) is likely to form but it is unstable in solution. The solid state molecular structures of [4]PF6, 5 and 6 were determined

The invention relates to heterocyclic compounds consisting of a core nitrogen atom surrounded by three pendant groups, wherein two of the three pendant groups are preferably benzimidazolyl methyl and tetrahydroquinolyl, and the third pendant group contains N and optionally contains additional rings. The compounds bind to chemokine receptors, including CXCR4 and CCR5, and demonstrate protective effects against infection of target cells by a human immunodeficiency virus (HIV).
