A series of acid-cleavable ester-type protecting groups, with acid-sensitivity profiles parallel to those of 2-naphthylmethyl (NAP) or p-methoxybenzyl (PMB) ether, were designed and TFA in toluene was identified as a technically simple and effective deblocking cocktail for their global removal in the context of oligosaccharide synthesis.
设计了一系列酸可裂解的酯型保护基,其酸敏感性与2-萘甲基(NAP)或对甲氧基苄基(PMB)醚的酸敏感性相似,并且在寡糖合成的背景下,甲苯中的三氟乙酸(TFA)被确定为一种技术上简单有效的脱保护混合试剂,用于整体去除这些保护基。
