- W1997935805 abstract "Die Morpholinenamine der Alloberbanon-Derivate 1a und 1b wurden mit Thiallium(III)-acetat zu den α-Acetoxyketonen 1c, 1d und 4a oxidiert. Die Reaktionen der Bromverbindung 1f mit Kaliumacetat und Kalium-3,4,5-trimethoxybenzoat werden diskutiert. Das zur Synthese von Despyrroloreserpin-Derivaten bedeutsame Zwischenprodukt 4c wurde in guter Ausbeute hergestellt. Investigations on the Chemistry of Berbans, V. — Synthesis of 18-Acyloxy-10,11-dimethoxy-(depyrrolo)alloyohimbinones The morpholine enamines of the alloberbanone derivatives 1a and 1b were oxidized with thallium(III) acetate to give the α-acetoxy ketones 1c, 1d and 4a. The reaction of the bromine compound 1f with potassium acetate and potassium 3,4,5-trimethoxybenzoate is discussed. The intermediate 4c, important for the synthesis of depyrroloreserpine derivatives, was obtained in good yield." @default.
