  Oxidative reactions of azines

  摘要：

  Oxidative coupling of 1-alkyl(benzyl)-4-(gamma-Pyridyl)-1,2,5,6-tetrahydropyridines with acetone in the presence of KMnO4 follows two pathways and yields both 1-R-2-(acetylmethylene)tetrahydropyridines and 1-R-3,4-dihydroxypiperidin-2-ones. When acetonitrile is used instead of acetone, the reaction under similar conditions occurs as selective ketodihydroxylation of the starting piperideines yielding 1-R-3,4-dihydroxy-4(gamma-Pyridyl)piperidin-2-ones . The molecular and crystal structures of one of these products (R = Et) was studied by X-ray diffraction analysis.

  been proposed to proceed via a polar pathway, an initial single-electron transfer pathway and an initial hydrogen atom transfer pathway. Results from previous studies on selected N-cyclopropyl-4-substituted-1,2,3,6-tetrahydropyridine derivatives have led us to consider a mechanism for these cyclic tertiary allylamines which may not necessarily involve the aminyl radical cation as required by an initial

  Fe+3 (1,10-phenanthroline)3 as the electron acceptor] and HAT pathway (using the tert-butoxyl radical as the hydrogen atom acceptor). The rates of oxidation and deuterium isotope effects observed with these compounds were similar with the two model reactions. Consequently, unlike their utility in modeling the related cytochrome P450 catalyzed alpha-carbon oxidation of N,N-dimethylaniline derivatives

  已经提出了MAO-B催化的胺的α-碳氧化可通过单电子转移（SET）或氢原子转移（HAT）途径进行。为了试图区分这些途径，我们使用化学模型检查了一系列4-取代的1-甲基-1,2,3,6-四氢吡啶衍生物（为MAO-B底物的化合物）的α-碳氧化SET途径[使用Fe + 3（1,10-菲咯啉）3的PF-6盐作为电子受体]和HAT途径（使用叔丁氧基作为氢原子受体）。用这些化合物观察到的氧化和氘同位素速率与两个模型反应相似。因此，与它们在建模相关细胞色素P450催化的N，N-二甲基苯胺衍生物的α-碳氧化中的用途不同，

  The substrate properties of a series of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridinyl (MPTP) analogues in which the C-4 phenyl group has been replaced with various 4-azaaryl moieties have been examined in an effort to evaluate the contribution of electronic, polar, and steric parameters to the MAO-B-catalyzed oxidation of this type of cyclic tertiary allylamine to the corresponding dihydropyridinium metabolite. No significant correlation could be found nit-h the calculated energy of the C-H bond undergoing cleavage. A general trend, however, was observed between the magnitude of the log P value with the magnitude of k(cat)/K-m. The results indicate that the placement of a polar nitrogen atom in the space occupied by the phenyl group of MPTP leads to a dramatic decrease in substrate properties. Enhanced substrate properties, however, were observed when benzoazaarenes replaced the corresponding five-membered azaarenes. These results are consistent with our previously published molecular model of the active site of MAO-B.
