[reaction: see text] Starting from (-)-quinic acid an efficient synthesis of highly functionalized cis-alpha,beta-unsaturated ketone 3, an advanced precursor of branimycin, has been accomplished via two key step reactions: a ring closing metathesis reaction to prepare the cis-decalin system, and a highly stereoselective epoxidation reaction.
[反应:请参阅文本]从(-)-奎尼酸开始,已通过两个关键步骤反应有效合成了高度官能化的顺式α,β-不饱和酮3(布雷尼霉素的先进前体)。制备顺式十氢化萘系统和高度立体选择性的环氧化反应。
