标 题:Resolution of racemic reticuline and racemization of its enantiomers

摘要:Racemic reticuline is resolved by forming a crystalline diastereomeric acid salt with a mandelic acid enantiomer. The reticuline enantiomers are racemized by treatment with a reduced noble metal or noble metal oxide catalyst. (-)-Reticuline is a valuable intermediate useful in the synthesis of thebaine, and (+)-reticuline is useful as a precursor of pallidine, sinoacutine, coreximine, and the berberine alkaloids.
