An efficient stereoselective total synthesis of (+)-Cephalosporolide D from commercially available and
inexpensive starting material, (±)-propylene epoxide, is described. The key steps involved in this synthesis are α-
aminoxylation catalyzed by L-proline, followed by in situ reduction using NaBH4 and Yamaguchi macrolactonization.
本文介绍了一种高效的立体选择性全合成 (+)- 头孢内酯 D 的方法,其起始原料(±)-环氧丙烷可从市场上买到,且价格低廉。该合成的关键步骤是在 L-脯氨酸催化下进行 α- 氨基酰化,然后使用 NaBH4 原位还原和 Yamaguchi 大内酯化。
