The ethyl carbamate of norpandamarilactonine-A was prepared in an enantiomerically pure form starting from (S)-prolinol. Deprotection of the amine functionality rendered both diastereomeric norpandamarilactonines as racemates, which were used as synthetic precursors of pandamarilactonine-A and -B.

从 (S)-脯氨醇开始,以对映体纯的形式制备去甲潘丹马里内酯-A 的氨基甲酸乙酯。胺官能团的脱保护使非对映异构体去甲熊猫内酯均成为外消旋物,用作熊猫内酯-A和-B的合成前体。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
