A1,3-strain enabled retention of chirality during bis-cyclization of β-ketoamides: total synthesis of (−)-salinosporamide A and (−)-homosalinosporamide A
摘要:
本文介绍了一种简明的对映体选择性合成 I 期抗癌剂 (â)-salinosporamide A 的方法。所描述策略的简洁性源于δ-酮三级酰胺的关键双环化,这种双环化是在克级规模上完成的,通过A1,3-应变保持了光学纯度,使得外延化相对于双环化的速度较慢。(â)-homosalinosporamide A 的合成证明了该策略在衍生物合成方面的多功能性。
