  摘要：

  AR-15512（以前称为 AVX-012 和 WS-12）是一种 TRPM8 受体激动剂，目前处于治疗干眼症的 2b 期临床试验中。这种具有类似薄荷醇清凉活性的生物活性化合物具有三个立体中心，其最终结构和绝对构型（1 R ,2 S ,5 R ）先前已通过冷冻电子显微镜解析。 AR-15512 的合成路线也已被报道，揭示了 C-1 的差向异构过程可能发生在合成的特定阶段。为了确认 AR-15512 的所需构型在整个过程中不会发生变化，并排除由于初始起始原料可能受到污染而导致最终产品中存在的对映异构体，AR-15512 的对映异构体和非对映异构体在C-1处进行了合成并充分表征。此外，通过X射线晶体学分析确定了( 1S ， 2S ， 5R )-非对映异构体的绝对构型，并设计和开发了新的HPLC方法来鉴定这两种立体异构体并与临床进行比较。候选者 AR-15512。

• PROCESS FOR MAKING NEO-ENRICHED p-MENTHANE COMPOUNDS

  公开（公告）日：2012-05-10

  A process for making neo-enriched p-menthane intermediates is disclosed. Lewis acid-catalyzed rearrangement of an oxaspiro compound provides an aldehyde mixture comprising normal (II) and neo (III) p-menthane-3-aldehydes: with the neo aldehyde (III) as the major product. The aldehyde mixture is readily oxidized to provide the corresponding carboxylic acids, and the acids are easily converted to a host of neo-enriched p-menthane esters or amides. The esters and amides are valuable as physiological coolants.

  公开了一种制备富含新生代p-薄荷醛中间体的方法。Lewis酸催化的氧杂螺环化合物重排提供了一种包含正常(II)和新生代(III) p-薄荷醛的醛混合物：其中新生代醛(III)是主要产物。这种醛混合物容易被氧化成相应的羧酸，而这些酸则容易转化为大量的富含新生代p-薄荷酯或酰胺。这些酯和酰胺作为生理降温剂非常有价值。

  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。
