from the corresponding substituted norketamines. Few of the latter have been reported since they have not been generally accessible via known routes. We report a new generalroute to many of these norketamines via the Neber (oxime to α-aminoketone) rearrangement of readily available substituted 2-phenycyclohexanones. We explored the use of the substituents Cl, Me, OMe, CF3, and OCF3, with a wide range
由相应的取代去甲氯胺酮制备了一系列苯环取代的氯胺酮N-烷基酯。后者很少被报道,因为它们通常不能通过已知的路线访问。我们报告了通过容易获得的取代 2-苯环己酮的 Neber(肟到 α-氨基酮)重排来制备许多这些去甲氯胺酮的新通用途径。我们探索了在所有可用的苯环位置使用具有广泛亲油和电子特性的取代基 Cl、Me、OMe、CF3 和 O 。2-和3-取代的化合物通常比4-取代的化合物活性更高。最普遍可接受的取代基是 Cl,而强大的吸电子取代基 和 O 提供的有效类似物较少。

An efficient and direct Cu-assisted nitrating approach to create synthetically valuable and challenging tertiary α-nitro-α-substituted moieties has been developed using cericammoniumnitrate as a nitrating reagent, oxidant, and Lewis acid. Notably, the commonly used clinical drug ketamine was smoothly synthesized in four steps.
