An efficient synthesis of 2,5-dihydrobenzoxepine analogues was developed without using protecting groups. Regioselective allylation was optimized through a recent method utilizing magnesium dicarboxylates. Grubbs catalysts were applied to investigate ring-closing metathesis. The scope of the present route was extended to produce four analogues, which provided novel cannabinoid-like 2,5-dihydrobenzoxepines
开发了一种不使用保护基团的 2,5-二氢苯并氧杂环庚烷类似物的有效合成方法。区域选择性烯丙基化通过最近使用二羧酸镁的方法进行了优化。Grubbs 催化剂用于研究闭环复分解。本路线的范围扩大到生产四种类似物,这些类似物提供了足够数量的新型大麻素样 2,5-二氢苯并氧西平,以允许对重组 CB1/CB2 受体进行体外测定。与 CB1/CB2 受体相关的体外试验未显示任何活性。
