The synthesis of four deuterated sialic acids and their 1,7-lactones has been performed in two ways, one based on sialic acid classical chemistry, and the other involving a direct exchange of the unlabeled acyl group of N-acetylneuraminic acid with a labeled one mediated by a perfluorinated amide. The final lactonization is promoted by benzyloxycarbonyl chloride.
四种氘代唾液酸及其1,7-内酯的合成已通过两种方式进行,一种基于唾液酸经典化学方法,另一种涉及将N-乙酰神经氨酸未标记的酰基与标记的一种直接交换。由全氟化酰胺介导。最终的内酯化由苄氧羰基氯促进。
