A series of new 3,4-ethylenedioxy-2-thenyl (EDOTn) derived alcohols have been synthesized and evaluated as super acid labile carboxylic acid protecting groups. All the derivatives are labile to very low concentrations of TFA (0.01–0.5%).
合成了一系列新的3,4-亚乙二氧基-2-乙烯基(EDOTn)衍生的醇,并将其评估为超强酸不稳定的羧酸保护基。所有衍生物都对低浓度的TFA(0.01–0.5%)不稳定。
