[reaction in text] Straightforward total syntheses of (-)-rosmarinecine have been achieved from L-malic acid derived pyrroline N-oxides by two novel useful cascade processes, which join the family of domino reactions. Both strategies, which furnished the target alkaloid in enantioenriched and enantiopure forms, respectively, allow complete control of configuration at all the three newly created contiguous
[文字中的反应]通过两个新的有用的级联方法,从L-苹果酸衍生的吡咯啉N-氧化物实现了直接合成(-)-迷迭香碱的方法,该方法加入了多米诺反应家族。两种策略分别以对映体富集和对映纯的形式提供目标生物碱,这两种策略都可以完全控制所有三个新近建立的连续立体中心的构型。
