We disclose herein a new approach for the highly diastereoselective total synthesis of the anti-tumoral agent (±)-Spisulosine. The synthesis was accomplished in seven steps with an overall yield of 10%. The key step involves the transformation of a Morita–Baylis–Hillman into an acyloin, which was subsequently used as substrate in a highly diastereoselective reductive amination reaction.
我们在此公开了一种用于抗肿瘤剂(±)-螺磺洛辛的高度非对映选择性全合成的新方法。合成以七个步骤完成,总产率为10%。关键步骤涉及将Morita–Baylis–Hillman转化为酰基lo,随后将其用作高度非对映选择性还原胺化反应的底物。
