An approach to the stereocontrolled synthesis of the protected form of sphingofungin E (32) starting from the known protected d-glucose derivative 3 is described herein. For the construction of a tetrasubstituted carbon atom that is substituted with nitrogen, the [3,3]-sigmatropic rearrangement of thiocyanate 8 was employed. Subsequent functional group interconversions afforded the highly functionalized
本文描述了从已知的被保护的d-葡萄糖衍生物3开始的立体控制合成的鞘氨醇单蛋白E(32)的保护形式的方法。为了构造被氮取代的四取代的碳原子,使用了硫氰酸酯8的[3,3]-σ重排。随后的官能团相互转化提供了高度官能化的片段,烯丙基溴26。其与已知的C(12)疏水链段2的偶联反应,然后进行进一步的操作,完成了总合成。
