• Nickel‐Catalyzed Cross‐Coupling of Aryl Bromides with Tertiary Grignard Reagents Utilizing Donor‐Functionalized N‐Heterocyclic Carbenes (NHCs)

  substrates represents a major challenge of the present cross‐coupling methodology. The nickel‐catalyzed Kumada cross‐ coupling of tertiary alkyl Grignard reagents with aryl bromides allows this difficult reaction with numerous different substrates. Optimal results were obtained using sterically demanding, bifunctional N‐heterocyclic carbene ligands.

  一二三 空间位阻烷基底物的利用代表了目前交叉偶联方法的主要挑战。叔烷基格氏试剂与芳基溴的镍催化的Kumada交联使得这种困难的反应可与多种不同的底物进行。使用空间要求高的双功能N杂环卡宾配体可获得最佳结果。

  The present invention provides synthetic routes for preparing various isomers of cyclohexane-based coolants, such as menthyl esters and menthanecarboxamide derivatives, in particular those substituted at the amide nitrogen, for example with an aromatic ring or aryl moiety. Such structures have high cooling potency and long lasting sensory effect, which make them useful in a wide variety of consumer products. One synthetic route involves a copper catalyzed coupling of a primary menthanecarboxamide with an aryl halide, such reaction working best in the presence of potassium phosphate and water. Using this synthetic route, specific isomers can be prepared including the menthanecarboxamide isomer having the same configuration as l-menthol and new isomers such as a neoisomer having opposite stereochemistry at the carboxamide (C-1) position. The neoisomer unexpectedly has potent and long lasting cooling effect. Preparation schemes for neoisomers of other menthyl derivatives which are useful as coolants, including esters, ethers, carboxy esters and other N-substituted carboxamides are also provided.

  本发明提供了合成路径，用于制备基于环己烷的各种异构体冷却剂，例如薄荷酯和薄荷烷甲酰衍生物，特别是那些在酰胺氮上取代的，例如带有芳香环或芳基的。这些结构具有高冷却效能和持久的感官效果，使它们在各种消费品中有用。一种合成路径涉及使用铜催化剂将一种初级薄荷烷甲酰胺与芳香卤代烃偶联，这种反应在存在磷酸钾和水的情况下效果最佳。利用这种合成路径，可以制备特定的异构体，包括具有与l-薄荷醇相同构型的薄荷烷甲酰胺异构体以及具有在羧酰胺（C-1）位置上相反立体化学的新异构体，该新异构体意外地具有强效和持久的冷却效果。还提供了其他薄荷衍生物的新异构体的制备方案，这些衍生物包括酯类、醚类、羧酯类和其他N-取代羧酰胺，它们也可用作冷却剂。
