d-erythro-Sphingosine (1) and phytosphingosine (2) have been efficiently synthesized from d-glucosamine by utilizing its whole carbon skeleton and functional groups. In this synthetic route, regioselective alkylation of the epoxy-tosylate 9 was achieved with a copper(I)-catalyzed Grignard reagent to give the key intermediate 10, which was converted to both 1 and 2via regioselective formation of the
D-赤-Sphingosine(1)和植物鞘氨醇(2)已经从d-葡糖胺通过利用它的整个碳骨架和官能团有效地合成。在该合成途径中,用铜(I)催化的格氏试剂实现环氧甲苯磺酸酯9的区域选择性烷基化,得到关键中间体10,其通过碘代醇11的区域选择性形成转化为1和2。
