Intramolecular cycloaddition of the syn- and the anti-nitrone 9 and 13 leads stereoselectively to the azabicyclic compounds 10 and 14 which may provide access to both enantiomers of the quinolizidine alkaloid lasubine II.
顺式和反式亚硝酮 9 和 13 的分子内环加成反应具有立体选择性,生成了稠合双环化合物 10 和 14,这可能为喹诺里西啶生物碱拉斯汀 II 的两种对映异构体提供了途径。
