标 题:Resolution of racemic reticuline and racemization of its enantiomers
发明人:SOHAR PAUL; SCHOENEWALDT ERWIN F
权利人:MERCK & CO INC
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.

摘要:The invention relates to sinomenine derivatives, methods for their synthesis and their applications. The sinomenine derivatives include oxidation derivatives, and C-10 substituted sinomenine derivatives. Based on the readily oxidizable phenol group on sinomenine structure, using oxidation, oxidative dearomatization, or conjugated addition aromatization, one can introduce C-10 substitutions to synthesize the sinomenine derivatives. The sinomenine derivatives of the invention have the following structures: n n n n n n n n n n Using in vitro TNF-α inhibition assay, the activities of the synthetic compounds are assessed. Results from these assays shown that most compounds have anti-inflammatory effects, and some compounds have better activities than that of sinomenine. These compounds may be used in treating immune diseases such as rheumatoid arthritis (RA).
