Alkyl chloroformates induced indirect trapping of the retroconjugate addition reaction intermediate involved in the epimerization of lobeline is described. This strategy was applied to the conversion of (−)-lobeline to (−)-sedamine in high overall yield.
描述了烷基氯甲酸酯诱导的间接捕集参与lobeline差向异构化的逆向共轭加成反应中间体。将该策略应用于以高总收率将(-)-小叶碱转化为(-)-二胺。
