  Stereochemical studies on the cytochrome P-450 catalyzed oxidation of (S)-nicotine to the (S)-nicotine .DELTA.1'(5')-iminium species

  摘要：

  Mammals metabolize the tobacco alkaloid (S)-nicotine primarily to the lactam (S)-cotinine by a pathway involving an initial cytochrome P-450 catalyzed two-electron oxidation at the prochiral 5'-carbon atom. The stereochemical course of this oxidation was examined with human microsomal preparations and the E and Z diastereomers of (S)-nicotine-5'd1. The metabolically generated delta 1'(5')-iminium ion intermediate was trapped and analyzed as the corresponding diastereomeric 5'-cyano derivatives by a capillary column GC-EIMS selected ion monitoring assay. The results of these studies established that this biotransformation proceeds with the stereoselective abstraction of the 5'-pro-E proton, that is, the C-5' proton trans to the bulky pyridyl group. The observed stereoselectivity was independent of proton vs. deuteron abstraction. Additionally, the extent of (S)-cotinine formation was minor and did not influence the stereochemical composition of the metabolically derived alpha-cyano amines. Studies with male Dutch rabbit liver microsomal preparations gave similar results. These findings suggest that the structure of the complex formed between (S)-nicotine and the active site of cytochrome P-450 is highly ordered and dictates the stereochemical course of the reaction pathway.

  A highly efficient metal‐free catalytic system for the aerobic photocyanation of tertiary amines with visible light is reported. The use of air as terminal oxidant offers an improved safety profile compared with pure oxygen, the used compact fluorescent lamp (CFL) light sources are highly economical, and no halogenated solvents are required. This system not only proves to be effective for a wide variety

  报道了一种高效的无金属催化体系，用于可见光下叔胺的有氧光致氰化。与纯氧相比，使用空气作为终端氧化剂可提高安全性，所使用的紧凑型荧光灯（CFL）光源非常经济，并且不需要卤化溶剂。该系统不仅证明对多种三烷基胺，药物和生物碱有效，而且显着还使有机染料有史以来最低的催化剂负载量（0.00001 mol％或0.1 ppm）。对获得的α-氨基腈进行了Bruylants反应和C-烷基化/脱氰，以证明复杂分子的后功能化。

  日期：——

  Visible light induced oxidative C–H functionalisation of tertiary amines catalysed by the combination of graphene oxide and Rose Bengal was developed. This reaction avoids the use of stoichiometric amounts of peroxy compounds as terminal oxidants. This reaction is useful for tri-alkyl amines including chiral tertiary amines. Both cyanide and trifluoromethyl nucleophiles were shown to participate in this reaction, providing α-cyano- and α-trifluoromethylated tertiary amines.

  在氧化石墨烯和玫瑰红的共同催化下，开发了可见光诱导的叔胺氧化 CâH 功能化。该反应避免了使用过氧化合物作为末端氧化剂。该反应适用于包括手性叔胺在内的三烷基胺。氰化物和三氟甲基亲核物均可参与该反应，提供δ-氰基和δ-三氟甲基化叔胺。
