A new approach to the synthesis of sphingoid bases has been developed. The strategy is based on Sonogashira coupling of a chiral acetylenic carbamate that can be prepared in enantiomerically enriched form from 2,3-epoxy-4-pentyn-1-ol, which is readily accessible by Sharpless asymmetric epoxidation. Several N-Boc-sphingadienines and aromatic ceramide analogs have been synthesized.
已经开发了一种新的合成鞘氨醇碱基的方法。该策略基于手性炔属氨基甲酸酯的Sonogashira偶联,可以从2,3-环氧--4-戊炔-1-醇以对映体富集的形式制备,可通过Sharpless不对称环氧化轻松获得。已经合成了几种N -Boc-鞘氨醇二烯和芳香族神经酰胺类似物。
