regioselectivity of the macrocyclic intramolecular nitrile oxide cycloaddition observed in our (+)-brefeldin A synthesis. During the course of this regiochemical study, we have developed two novel stereoselective and regioselective schemes for total synthesis of (+)-brefeldin A (i.e. intramolecular nitrile oxide cycloaddition-isomerization and intermolecular nitrile oxide cycloaddition-ring closing metathesis
我们已经了解到构象效应对在我们的(+)-布雷菲德菌素A合成中观察到的大环分子内腈氧化物环加成反应的区域选择性的作用。在该区域化学研究的过程中,我们开发了两种新颖的立体选择性和区域选择性方案,用于全合成(+)-布雷菲德菌素A(即分子内一氧化氮环加成异构化和分子间一氧化氮环加成环封闭复分解策略)。
