text] The synthesis of a six-carbon truncated sialic acid is described. A key step in the synthesis was an indium-mediated allyl addition to a serine-derived aldehyde. Careful choice of protecting groups was found to be necessary in order to prevent unwanted side reactions throughout the sequence. The truncated sialic acid was obtained in a form suitable for activation as a glycosyl donor.
[反应:见正文]描述了六碳截短的唾液酸的合成。合成中的关键步骤是将铟介导的烯丙基添加到丝氨酸衍生的醛中。发现必须仔细选择保护基,以防止整个序列中不希望的副反应。以适于活化为糖基供体的形式获得截短的唾液酸。
