We report here the first example of an SRN1 reaction on propargylic chloride in heterocyclic series. The reaction of 4-(3-chloroprop-1-ynyl)-1,2-dimethyl-5-nitro-1H-imidazole with nitronate anions led to both the formation of the C-alkylated product through an SRN1 mechanism and the predominant ethylenic compound resulting from nitrous acid elimination on the C-alkylated product. Interestingly, in
我们在此报告杂环系列中炔丙基氯上S RN 1反应的第一个例子。4-(3-氯丙-1-炔基)-1,2-二甲基-5-硝基-1 H-咪唑与亚硝酸根阴离子的反应导致通过S RN 1机理形成C-烷基化产物和由亚烷基消除C-烷基化产物产生的主要烯类化合物。有趣的是,与我们先前关于S RN 1反应性的研究相反,没有观察到O-烷基化的产物。
