A new triazinone-based reagent for O-p-methoxybenzylation has been developed. In spite of its stability in solid form, this reagent converts a free alcohol into the corresponding p-methoxybenzyl ether with mild heating (50–60 °C) in a solution. High functional group tolerance can be achieved because the reaction does not require the addition of an acidic or basic activator.
新三嗪酮为基础的试剂Ø - p -methoxybenzylation已经研制成功。尽管它以固体形式稳定,但在溶液中温和加热(50–60°C)时,该试剂可将游离醇转化为相应的对甲氧基苄基醚。可以实现高官能团耐受性,因为该反应不需要添加酸性或碱性活化剂。
A Mild and Versatile Method for the Synthesis of Alkyl Ethers from Methoxymethyl Ethers and Application to the Preparation of Sterically Crowded Ethers
A mild and divergent route for the synthesis of alkylethersfrommethoxymethyl (MOM) and methoxyethyl (ME) ether derivatives via pyridinium‐type salt intermediates has been developed. The addition of organocuprates to the salts afforded the corresponding alkylethers, including highly crowded ones, in high yields even in the presence of acid‐ or base‐sensitive functional groups.
