The carboxylic acid functionality can be protected as the 1,2,3,4-tetrahydro-1-naphthyl ester, which can be selectively cleaved in the presence of aryl and alkyl esters using chlorotrimethylsilane and sodium iodide in acetonitrile. This protecting group allows room temperature deprotection under essentially neutral conditions throughout the cleavage reaction.
羧酸官能团可以被保护为1,2,3,4-四氢-1-萘酯,该酯可以在芳基和烷基酯存在下,使用三甲基氯硅烷和碘化钠在乙腈中进行选择性裂解。该保护基团允许在整个裂解反应中在基本上中性的条件下在室温下脱保护。
