The arylene–ethynylene arrays involving pyridine were constructed successfully by taking advantage of double elimination reaction of β-substituted sulfones (sulfoximines) which are easily accessible from arylmethyl sulfones (sulfoximines) and aromatic aldehydes. This protocol was utilized for synthesis of an enantiopure arylene–ethynylene framework bearing a binaphthyl stereogenic core.
成功构建了涉及
吡啶的芳基-炔基阵列,利用了β-取代磺酰胺(磺
酰亚胺)的双重消除反应,这些磺酰胺可以从芳基甲基磺酰胺(磺
酰亚胺)和芳香醛中轻松获取。该方法用于合成具有二
萘基立体中心的对映纯芳基-炔基框架。
