Selected compounds are effective for prophylaxis and treatment of diseases, such as angiogenesis mediated diseases. The invention encompasses novel compounds, analogs, prodrugs and pharmaceutically acceptable salts thereof, pharmaceutical compositions and methods for prophylaxis and treatment of diseases and other maladies or conditions involving, cancer and the like. The subject invention also relates to processes for making such compounds as well as to intermediates useful in such processes.
this is deoxygenated to the sulfide by LR at room tmeperature. 1-Phthalazinone-4-thione, 1,4-phthalazine-dithione and ethyl aminothioxoacetate have also been prepared from the corresponding carbonyl compounds. Alkylation or acylation of 2a–d yielded 3H-pyrazole-3-thione derivatives 8 and 9. Alkylation of 1 with MeI in the presence of Et3N at room temp. yielded the C-alkylated products 10 exclusively. X-RAy
studies. Furthermore, time-dependent electrospray ionization mass spectrometry (TD ESI-MS) was applied to track the process by detecting most intermediates. The complex [CuIII(iodobiphenyl)(bipy)I]+ (Int-C) was detected for the first time, giving evidence for oxidative addition of cyclic iodonium to Cu catalyst. Another complex [CuI(PHA)(bipy)] (Int-B) via ligand-exchange between the hydrazide and Cu catalyst
报道了一种酸酐促进的无痕肼-I/Br 交换策略,其中水合肼和环状/线性碘鎓(包括很少探索的环状溴鎓)在一个锅中转化为苯并 [ c ] 肉啉/偶氮苯。该反应通过二酰化(第一和第二个 C─N 形成)、 N , N'-二芳基化(第三和第四个 C─N 形成)和脱酰/氧化(2 个 C─N 裂解和 1 个 N=N 形成)进行。通过分离多个中间体和动力学研究来研究反应机理。此外,应用时间依赖性电喷雾电离质谱 (TD ESI-MS) 通过检测大多数中间体来跟踪过程。络合物 [Cu III (iodobiphenyl)(bipy)I] + (Int-C )首次被检测到,为环碘鎓氧化加成Cu催化剂提供了证据。还检测到另一种络合物 [Cu I (PHA)(bipy)] ( Int-B ) 通过酰肼和 Cu 催化剂之间的配体交换,表明双路径初始活化过程。
