Deuterium- and tritium-labeled d-erythro-sphingosine (1b and 1c) were prepared by an efficient approach based on a known stereoselective total synthesis. Tritium was introduced at C−1 by [3H]NaBH4 reduction in the final synthetic step to give 1c of high radiochemical purity. 1,1,3-Trideuterio-d-erythro-sphingosine (1b) was prepared similarly and showed >99·5% enantiomeric purity and a high level of
氘和氚标记的 d-赤型鞘氨醇(1b 和 1c)是通过基于已知立体选择性全合成的有效方法制备的。在最后的合成步骤中,通过 [3H]NaBH4 还原在 C-1 处引入氚,得到高放射化学纯度的 1c。1,1,3-Trideuterio-d-erythro-sphingosine (1b) 的制备方法类似,并且显示出 >99·5% 的对映体纯度和高水平的氘掺入。版权所有 © 1999 John Wiley & Sons, Ltd.
