A novel method to synthesize 4-alkylpyrimidines by the mechanochemical magnesium-mediated Minisci reaction of pyrimidine derivatives and alkyl halides has been reported. The reaction process operates with a broad substrate scope and excellent regioselectivity under mild conditions with no requirement of transition-metal catalysts, solvents, and inert gas protection. The practicality of this protocol
已经报道了一种通过嘧啶衍生物和烷基卤化物的机械化学镁介导的 Minisci 反应合成 4-烷基嘧啶的新方法。该反应过程底物范围广,区域选择性好,条件温和,不需要过渡金属催化剂、溶剂和惰性气体保护。该协议的实用性已通过大规模合成、机械化学产品衍生化和抗疟药物乙胺嘧啶的制备得到证明。
