The ‘click synthesis’ of some novel O‐substituted oximes, 7a–7t, which contain 1,2,3‐triazolediyl residues, as new analogs of β‐adrenoceptor antagonists is described (Schemes 1–4). The synthesis of these compounds was achieved in four to five steps. The formation of oximes of 9H‐fluoren‐9‐one and benzophenone, i.e., 9a and 9b, respectively, followed by their reaction with propargyl bromide, afforded
一些新颖的“点击合成” ø取代的肟,7A - 7吨,其含有1,2,3-三唑二基,作为新的类似物β -肾上腺素能受体拮抗剂被描述(方案1 - 4)。这些化合物的合成需要四到五个步骤。9本肟的形成ħ芴-9-酮和二苯甲酮,即,图9a和图9b分别,得到随后通过它们与炔丙基溴反应ö -propargyl肟10A和10B,分别,其通过随后的CuI催化惠斯根用制备的β-叠氮基醇11a – 11j进行环加成反应(方案2和3),得到的目标化合物7a – 7t的收率很高。
