strategies for its synthesis to date have required multistep methods and have been very limited, such as the use of SNAr‐type reactions. Herein, we describe a synthetic methodology employing benzynes, 1,4‐diazabicyclo(2.2.2)octane (DABCO), and nitrogen nucleophiles to access these privileged organic compounds. The established protocol proved to be a transition‐metal‐free, mild reaction that proceeded via
2-(4-苯基哌嗪-1-基)乙-1-胺支架是结构上重要的基序,在药物和药物化学中经常出现。尽管该部分具有重要意义,但迄今为止,其合成的一般策略仍需要多步方法,并且非常局限,例如使用S N Ar型反应。在这里,我们描述了一种合成方法,该方法使用苯炔,1,4-二氮杂双环(2.2.2)辛烷(DABCO)和氮亲核试剂来访问这些特权有机化合物。业已证明的既定规程是无过渡金属的轻度反应,其反应是通过由苯甲酸和DABCO形成的季铵盐进行的。
