Darstellung und Reaktionen von 4-O-Methyl-salutaridin-methoperchlorat

Abstract

Methylation of Δ⁸⁽¹⁴⁾-7-oxo-thebainone-methoperchlorate (1) yields 4-O-methyl-salutaridine-methoperchlorate (2), which by action of 1n-NaOH is degradated to methine3. Acidic hydrolysis of2 at room temperature yields 7-hydroxy-4-O-methyl-7.8-dehydro-metathebainone-methoperchlorate (4 a), which by heating in 10n-HClO₄ solution can be rearranged to 7-hydroxy-4-O-methyl-morphothebaine-methoperchlorate (5). The structures of the new compounds2, 3, 4 a, and5 are proved.

Zusammenfassung

Durch Methylierung von Δ⁸⁽¹⁴⁾-7-Oxo-thebainon-methaperchlorat (1) wird 4-O-Methyl-salutaridin-methoperchlorat (2) erhalten, das beimHofmannabbau das Methin3 liefert. Einwirkung von konz. HCl auf2 bei Raumtemp. führt zu 7-Hydroxy-4-O-methyl-7.8-dehydro-metathebainon-methoperchlorat (4 a), aus dem beim Erwärmen mit 10n-HClO₄ 7-Hydroxy-4-O-methyl-morphothebain-methoperchlorat (5) entsteht. Die Strukturen von2, 3, 4 a und5 werden bewiesen.
