“…The oxidation of reserpine reported in 1994 was the first reaction of a benzylic amine with IBX ever reported. [149] Detailed investigations by Nicolaou et al later demonstrated the generality of IBX-mediated oxidations of benzylic amines; in a reaction that parallels the oxidation of alcohols to carbonyl compunds, benzylic amines are transformed into the respective imines (Scheme 27). [147,150] The remarkable chemoselectivity of this transformation allows the oxidation of secondary benzylic amines even in the presence of primary alcohols or free phenols.…”

“…Die Möglichkeit, benzylische Amine mit IBX zu oxidieren, wurde erstmals 1994 für die spezifische Oxidation von Reserpin berichtet. [149] Nicolaou et al zeigten später in detaillierten Untersuchungen, dass die IBX-vermittelte Oxidation benzylischer Amine ein genereller Prozess ist; in Analogie zur Oxidation von Alkoholen zu Carbonylverbindungen werden benzylische Amine in die entsprechenden Imine überführt (Schema 27). [147,150] [151] In Gegenwart eines Alkens wäre die typischerweise zur Entschützung von benzylierten Aminen verwendete Hydrierung nicht gelungen, ohne auch die Doppelbindung einzubüßen.…”

“…B. bei der quantitativen Bestimmung bestimmter Thiole und Amine. [149,229] Auch die Oxidation von Phenolen zu Chinonen wurde schon früh für den qualitativen und quantitativen Nachweis freier phenolischer Hydroxygruppen genutzt. [230] Angesichts ihrer von Anfang an bekannten oxidierenden Eigenschaften erscheint es nicht überraschend, dass IBA und IBX in zu Beginn des 20.…”

“…Therefore, simultaneous determination of the analytes in biological samples is important in studying pharmacokinetics. However, to our best knowledge, no analytical method has been described in the literature which simultaneously determines these three analytes in biological samples, even though several methods exist, which separately determine either triamterene [1][2][3][4][5], hydrochlorothiazide [6][7][8], reserpine [9][10][11][12][13], or determine triamterene and hydrochlorothiazide simultaneously [14,15]. Though many kinds of analytical methods such as spectrophotometry, spectrofluorimetric, potentiometry, capillary electrophoresis, HPLC-UV, LC-MS were used in these literatures, it is tedious to determine three analytes separately for each sample using two different HPLC conditions or even two different detection methods.…”
