A mild and divergent route for the synthesis of alkyl ethers from methoxymethyl (MOM) and methoxyethyl (ME) ether derivatives via pyridinium‐type salt intermediates has been developed. The addition of organocuprates to the salts afforded the corresponding alkyl ethers, including highly crowded ones, in high yields even in the presence of acid‐ or base‐sensitive functional groups.
通过吡啶鎓盐类中间体,从甲氧基甲基(MOM)和甲氧基乙基(ME)醚衍生物合成烷基醚的温和而多样化的路线已被开发出来。向盐中添加有机铜盐即使在对酸或碱敏感的官能团存在的情况下,也能以高收率获得相应的烷基醚,包括高度拥挤的烷基醚。
