The short syntheses of each of the mono-acetates of N-acetyl-D-neuraminic acid are reported. These are important molecules for studying the mechanism and function of enzymes which utilise Neu5Ac as a substrate. However, until now these molecules were not available as pure compounds and instead had to be studied as mixtures. Neu4,5Ac2 and Neu5,8Ac2 were synthesised from a common precursor in 2 and 4
每种单乙酸盐的简短合成 N-乙酰基-D-神经氨酸被报道。这些是研究利用Neu5Ac作为底物的酶的机制和功能的重要分子。但是,直到现在,这些分子还不能以纯化合物形式获得,而是必须以混合物形式进行研究。Neu4,5Ac 2和Neu5,8Ac 2分别从一个普通的前体分2步和4个步骤合成,而Neu2,4Ac 2和Neu5,7Ac 2分别从另一个普通的前体分3个步骤和4个步骤合成。从Neu5Ac本身可以很容易地通过3个步骤制备两种前体。重要的是,在这些合成的整个过程中都没有检测到异头立体化学的混乱。
