sulfoxide–magnesium exchange, with primary alkyl halides in the presence of Cu(I) iodide as a catalyst, was realized. The alkylated aziridines were converted in quantitative yield to amines bearing a quaternary chiral center by hydrogenation with Pd(OH)2. A synthesis of the optically active amines, bearing a quaternary chiral center, was realized, starting from optically active (R)-chloromethyl p-tolyl sulfoxide
在亚碘化铜(I)作为催化剂的情况下,通过亚烷基卤与亚砜基氮丙啶通过亚砜-镁交换由EtMgBr与亚甲基吡啶形成的高产率烷基化反应得以实现。通过用Pd(OH)2氢化,将烷基化的氮丙啶以定量收率转化为带有季手性中心的胺。通过所提出的方法,从旋光的(R)-氯甲基对甲苯基亚砜开始,实现了具有季手性中心的旋光的胺的合成。
