(±)-Isofagomine (1) and all its stereoisomers were prepared in a short synthesis from arecoline. The double bond of arecoline was isomerised to be no longer conjugated to the carboxy, and the ester reduced to (hydroxymethyl)tetrahydropyridine 5 which after dihydroxylation of the alkene, separation and N-demethylation gave 1 and its isomers.
(±)-Isofagomine (1) 及其所有立体异构体都是由异甲氧苄啶通过简短的合成方法制备的。异构化后的异胆碱双键不再与羧基共轭,酯还原成(羟甲基)四氢吡啶 5,经过烯烃二羟基化、分离和 N-去甲基化后得到 1 及其异构体。
