A new route for the synthesis of the cytotoxic anhydrosphingosine pachastrissamine has been developed. [3.3] Sigmatropic rearrangement of an allyl cyanate was employed to construct the allyl amine moiety in 2 from the chiral C-4 unit 3. Oxidative cleavage of the double bond in 2, followed by THF ring formation furnished the target pachastrissamine.
已经开发了合成细胞毒性脱水鞘氨醇pachastrissamine的新途径。[3.3]烯丙基氰酸酯的σ迁移重排用于构造烯丙基胺部分在2从手性C-4单元3。2中双键的氧化裂解,然后形成THF环,提供了目标pachastrissamine。
