A new formacetal linkage (ROCH2OR′) forming reaction was developed, which exploited a combination of sulfide (R′OCH2SR″) and CuBr2-Bu4NBr. This reaction proceeded to give high yields under neutral conditions and was applied to the protection of alcohols, phenols and carboxylic acids by several types of α-oxymethyl groups.
利用硫化物(R'OCH 2 SR”)和CuBr 2 -Bu 4 NBr的组合,开发了一种新的甲醛缩醛键(ROCH 2 OR')形成反应。该反应在中性条件下进行以得到高产率,并通过几种类型的α-氧甲基被用于保护醇,酚和羧酸。
