dimension of orthogonality for carboxylic acid protection. They can be deprotected under nearly neutral oxidative conditions. In this paper, the protection of carboxylic acid with dM-Dim, deprotection of dM-Dim ester with sodium periodate, stability of dM-Dim protected carboxylic acid under acidic and basic conditions, and selective deprotection of dM-Dim protected carboxylic acids in the presence of tertiary
1,3-二噻吩-2-基-甲基(Dim)及其类似基团(包括二甲基-Dim(dM-Dim))可以为羧酸保护提供新的正交性。它们可以在接近中性的氧化条件下脱保护。本文研究了用dM-Dim保护羧酸,用高碘酸钠对dM-Dim酯进行脱保护,在酸性和碱性条件下dM-Dim保护的羧酸的稳定性以及在dM-Dim保护的羧酸中的选择性脱保护。存在叔丁基和甲基酯。
