Starting from D-mannitol, the total syntheses of methyl 9(S)- and 9(R)-hydroxy 5(Z), 7(E), 11(Z) eicosatetraenoate are described by two different ways. One route uses a diepoxide opening by an acetylide while the second one involved the transformation of a diepoxide into an equivalent of malic aldehyde, an important intermediate in the synthesis of other oxidation products of arachidonic acid. Both methods
从D-甘露糖醇开始,通过两种不同方式描述了二十碳四烯酸甲酯9(S)-和9(R)-羟基5(Z),7(E),11(Z)的总合成。一种途径是通过乙炔化物打开二环氧化物,而第二种途径涉及将二环氧化物转化为等效的苹果醛,后者是花生四烯酸其他氧化产物合成的重要中间体。两种方法均可用于合成每种对映异构体。
