An unexpected access to a new sphingoid base containing a vinyl sulfide unit is described. The process involves the 'one-pot' regioselective opening of an epoxide with a thiolate, followed by intramolecular acyl transfer, base-promoted elimination, and final hydrolysis. Excess sodium hydride and high dilution conditions are required for optimal yields. The process is amenable to a variety of thiolates
描述了对含有乙烯基硫化物单元的新鞘氨醇碱的意外访问。该过程涉及环氧化物与硫醇盐的“一锅”区域选择性打开,然后是分子内酰基转移、碱基促进消除和最终水解。最佳收率需要过量氢化钠和高稀释条件。该过程适用于各种硫醇盐。由此产生的化合物可以被视为新的混合鞘氨醇碱基,它结合了其他报道的鞘脂类似物中存在的一些结构基序。
