  不含配体的铜（II）催化剂与配体辅助的Pd（II）催化剂通过C–H官能化形成分子内C–S键一样有效

  摘要：

  铜（I）催化剂通常是在另一方面将Pd（II）催化剂是促进分子内的SP相当有效无效2 C-H官能化（C-S键的形成）。在这里，我们已经开发了一种配体辅助的Pd（II），通过芳基硫脲的C–H活化来催化C–S键的形成，从而导致在芳基环上带有给电子（EDG）基团的底物形成2-氨基苯并噻唑。然而没有协助配体该Pd（II）催化的反应是相当非生产性特别是对于硫脲具有强供电子基团中的芳环。有趣的是，无配体的Cu（II）催化的芳基硫脲的氧化环化对于在芳环上具有给电子基团和吸电子基团的芳基硫脲都同样有效。

  Thiourea analogs 1–20 were synthesized and evaluated for their in vitro β-glucuronidase inhibitory potential. The compounds 9 (0.86 ± 0.01 μM), 6 (1.24 ± 0.01 μM), 16 (1.64 ± 0.02 μM) and 15 (2.12 ± 0.02 μM) showed potent activity. Other analogs 1–5, 7, 8, 10, 11, 13, 17, 20 showed better activity than standard drug d-saccharic acid 1,4-lactone (47.34 ± 0.21 μM) ranging 4.36–34.4 μM. All synthetic

  N-Arylthioureas are converted to 2-aminobenzothiazoles via intramolecular C−S bond formation/C−H functionalization utilizing an unusual cocatalytic Pd(PPh3)4/MnO2 system under an oxygen atmosphere at 80 °C. This method eliminates the need for an ortho-halo substituted precursor, instead achieving direct functionalization of the ortho-aryl C−H bond. Mechanistic observations, including a large intramolecular

  日期：2009.4

  Cationic, chiral arene ruthenium complexes of the type [Ru(eta(6)-cym)(PPh3)kappa N-2,S-PhNC(S)R}]BPh4 were prepared in high yields by refluxing a mixture containing [(eta(6)-cym)RuCl2](2), Ph3P, PhNHC(S)R, NaBPh4 and Et3N in MeOH. A series of seven complexes with different thioamide ligands was prepared and fully characterised by spectroscopic methods including NMR spectroscopy and electrospray mass spectrometry. The solid-state structures of two complexes were determined by single crystal X-ray diffraction. (C) 2008 Elsevier B.V. All rights reserved.
• Synthesis of N-substituted-N-acylthioureas of 4-substituted piperazines endowed with local anaesthetic, antihyperlipidemic, antiproliferative activities and antiarrythmic, analgesic, antiaggregating actions

  日期：2003.9

  Three series of N-acyl and N-cyclohexyl- or N-methyl or N-phenyl-thioureas of 4-substituted (methyl, phenyl, 2-pyridyl)piperazines (4-12) were synthesised according to a highly convergent one-pot procedure and tested in vivo (local anaesthetic, anti-hyperlipoproteinemic, analgesic, anti-inflammatory, antiarrythmic activities) and in vitro (antiaggregating and, for some selected derivatives, antiproliferative activities) experiments. All the test compounds showed local anaesthesia in particular 4Ar(4), 5Ar(4), 12Ar(3) (after 5 min) and 5Ar(2), 5Ar(3), 9Ar(4) (after 30 min) were equipotent to lidocaine. In lowering triglyceride levels, compounds 6Ar(4) and 7Ar(3) were more active than nicotinic acid, whereas 7Ar(4) and 11Ar(4) were approximately equipotent. As concerns analgesic activity, 5Ar(2) and 5Ar(4) were as active as indomethacin. Appreciable anti-inflammatory activity was found in 8Ar(1), 5Ar(2) and 11Ar(2), but inferior to that of indomethacin. High levels of antiarrythmic activity, comparable with that of quinidine, were found in derivatives 4Ar(2) and 10Ar(1). Compounds 4Ar(2) and 8Ar(2), assayed in antitumor in vitro screening system at National Cancer Institute (NCI), showed significant antiproliferative activity against ACHN cell line (GI50: 0.13 microM) and NCI-H226 cell line (GI50: 1.03 microM), respectively.

  o-halogens (–F, –Cl) gave 2-aminobenzothiazoles via a dehalogenative heteroarylation path and not by the Hugerschoff path involving an electrophilic substitution reaction. For thioureas containing reactive ortho halogens (such as –Br, –I) the reaction proceeds at room temperature giving 2-aminobenzothiazoles via a dehalogenative path requiring a catalytic quantity of Cu(II). No transformation of thiourea (Tu)

  具有催化量的Cu（II）盐的2-卤代芳基-仲-烷基不对称硫脲（Tu）（卤代= -F，-Cl）原位氧化成其二硫键中间体，然后亚胺-二硫键重排得到硫代氨基胍基（标签）在室温下的部分。在此过程中，Cu（II）还原为Cu（I），并与Tag部分形成复合物，在用Mg处理后，可从中分离Tag部分。氨。但是，当在高温下用催化量的Cu（II）盐进行相同的反应时，带有邻卤素的Tu （-F，-Cl）通过脱卤杂芳化途径而不是通过Hugerschoff途径生成2-氨基苯并噻唑涉及亲电取代反应。对于含有反应性邻卤素（例如–Br，–I）的硫脲，反应在室温下进行，通过脱卤途径生成2-氨基苯并噻唑，需要催化量的Cu（II）。没有转变硫脲用Cu（I）盐观察到（Tu）至Tag，表明该氧化转化需要氧化Cu（II）盐。温和的反应条件，对环境有益的试剂和溶剂，高收率，对各种官能团的耐受性是该方法的一些基本特征。
