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.
描述了氯甲酸烷基酯诱导参与洛贝林差向异构化的逆共轭加成反应中间体的间接捕获。该策略被应用于以高总收率将(-)-洛贝林转化为(-)-塞达明。
