An efficient methodology for the synthesis of sphingoid-type bases is reported. It involves the stereoselective addition of a racemic 3-alkoxy allenylzinc to enantiopure N-tert-butylsulfinyl imines and a cross-metathesis reaction as the key steps. It has been successfully applied to the syntheses of sphinganine and naturally occurring bioactive related compounds, among which the hydrolysis product
报告了一种有效的合成类鞘氨醇型碱基的方法。它涉及将外消旋的3-烷氧基烯基锌立体选择性地添加到对映体纯的N-叔丁基亚磺酰基亚胺中,并且交叉复分解反应是关键步骤。它已被成功地用于合成狮身人参碱和天然存在的生物活性相关化合物,其中包括克拉维醇H和两种鞘脂的水解产物。所有这些化合物均由N-叔丁基亚磺酰基亚胺分六步制备,总收率高(> 56%)。
