D-erythro-Sphingosine (1) was synthesized from D-glucosamine (2) as a chiral pool through stereoinversion of the C(3)-hydroxyl group via an oxidation-reduction sequence, transformation to the erythro-amino-alcohol chiron (9) protected as the oxazolidinone, and elongation of the side chain at the C(6)-position of the derived chloride (12).
D-赤型-鞘氨醇 (1) 由 D-葡萄糖胺 (2) 作为手性池,通过氧化还原序列对 C(3)-羟基进行立体反转,转化为赤型氨基醇 Chiron (9 ) 被保护为恶唑烷酮,并在衍生的氯化物 (12) 的 C(6)-位处延长侧链。
