D-erythro-Sphingosine is synthesized from N-benzoyl-D-glucosamine 2 in a highly regio- and stereocontrolled manner. The key features in the synthesis involve the efficient conversion of compound 2 into the vinyl epoxide 10 and the subsequent SN2′-type reaction with a Grignard reagent in the presence of CuCN to afford the 1-O,2-N-protected sphingosine 11.
D-赤型-鞘氨醇由N-苯甲酰基-D-葡糖胺2以高度区域控制和立体控制的方式合成。合成中的关键特征包括化合物2有效转化为乙烯基环氧化合物10,以及随后在CuCN存在下与Grignard试剂进行S N 2'型反应,得到1- O,2- N保护的鞘氨醇11。
