Precursors of phospholipids or ether lipids were synthesized from D-mannitol, i.e., 1-O-myristoyl-2-O-benzyl-sn-glycerol 11 and 1-O-hexadecyl-2-O-benzyl-sn-glycerol 13. The chemical pathways involved sequential protection reactions using allyl, triphenylmethyl, or benzyl groups via 3-O-allyl-sn-glycerol. Eleven intermediates were isolated and for the first time characterized with their spectrometric (especially 1H nmr) and physical parameters and yield. This work allowed preparation of chemically defined membrane phospholipids from compound 11 as well as ether lipids from compound 13 with cell mediator activities bearing different probes such as photoactivatable, fluorescent, or radioactive groups.
磷脂或醚脂的前体物质是从D-甘露醇合成的,即1-O-肉豆蔻酰基-2-O-苄基-sn-甘油醇11和1-O-十六烷基-2-O-苄基-sn-甘油醇13。所涉及的化学途径涉及使用烯丙基、三苯甲基或苄基团进行顺序保护反应,通过3-O-烯丙基-sn-甘油醇。分离了十一个中间体,并首次通过其光谱学(尤其是1H核磁共振)和物理参数以及产率进行了表征。这项工作使得可以从化合物11制备化学定义的膜磷脂,以及从化合物13制备具有不同探针(如光活化、荧光或放射性基团)的细胞介质活性的醚脂。
