The synthesis of novel C11 chain-extended analogues of N-acetylneuraminic acid has been achieved from the N-acetyl-9-hydroxyneuraminic acid derivative 7 via a Swern oxidation/Wittig olefination sequence. In this way the novel α,β-unsaturated ester 12, the saturated ester 13 and the α,β-unsaturated aldehyde 14 of N-acetylneuraminic acid have been prepared in good overall yield.
通过 Swern 氧化/Wittig 烯化顺序,从 N-乙酰基-9-羟基神经氨酸衍生物 7 合成了新型的 N-乙酰基神经氨酸 C11 延长链类似物。这样就制备出了新型的 N-乙酰神经氨酸α,β-不饱和酯 12、饱和酯 13 和 α,β-不饱和醛 14,总体收率较高。
