    Thermisches und massenspektroskopisches Verhalten von Berberin und anderen Pseudobasen (1970)

    Description / Table of Contents: Thermic and Mass Spectroscopic Behaviour of Berberine and Other PseudobasesThe three possible types of pseudobases - immonium hydroxide, carbinolamine and aminoaldehyde - shows striking differences in their mass spectra. Carbinolamines undergo a thermal disproportionation into amide and amine, which gives rise to a “M - 14”-peak; aminoaldehydes form fragments characteristic for aldehydes, while with immonium hydroxides the favoured fragmentation reactions are the elimination of water and the splitting off of an OH-radical.
    Notes: Pseudobasen geben in Massenspektrum verschiedene Zerfallsschemata, je nachdem ob sie als Carbinolamin, als Aminoaldehyd oder als Immoniumhydroxid reagieren. Carbinolamine disproportionieren thermisch in Säureamid und Amin, wodurch eine “M - 14”-Spitze vorgetäuscht wird; bei Aminoaldehyden treten die charakteristischen Bruchstücke von Aldehyden auf, während bei den Immoniumhydroxiden die Eliminierung von Wasser und die Abspaltung eines OH-Radikals die Hauptfragmentierungsreaktionen sind.

    Description / Table of Contents: On the Toxins of Mediterranean Holothuriae, II1). The Aglycones of the Toxins of Holothuria poliiSix aglycones have been isolated from the toxins of the skin of Holothuria polii (Delle Chiaje) and their structures elucidated by means of spectroscopic data. The 22-O substituted compounds 1-3 have already been detected in other Holothurioideae. The remaining, as yet unknown, compounds, are holothurinogenin (4), 25-methoxyholothurinogenin (5), and 17-deoxy-25-methoxyholothurinogenin (6).  -  The hitherto unknown configuration at C-20 could be deduced from NMR-data.
    Notes: Aus den in der Haut von Holothuria polii (Delle Chiaje) enthaltenen Toxinen werden sechs Aglyka isoliert und auf spektroskopischem Wege in ihrer Struktur aufgeklärt. Die 22-O-substituierten Komponenten 1-3 waren bereits von anderen Holothurioideen her bekannt. Bei den bislang unbekannten Substanzen handelt es sich um Holothurinogenin (4), 25-Methoxy-holothurinogenin (5) und 17-Desoxy-25-methoxy-holothurinogenin (6).  -  Aus NMR-Daten ist die bisher ungeklärte Konfiguration an C-20 abgeleitet worden.

    Description / Table of Contents: Disproportionation of PseudobasesThe alkali-catalyzed disproportionation of pseudobases is, according to the experiments described, a heteroanalogous Cannizzaro reaction and is intermediate between the acid-catalyzed disproportionation of the benzhydrols and the alkali-catalyzed Cannizzaro reaction.
    Notes: Die durch Alkali katalysierte Disproportionierung der Pseudobasen stellt nach den vorliegenden Untersuchungen eine heteroanaloge Cannizzaro-Reaktion dar und nimmt eine Mittelstellung zwischen der sauer katalysierten Disproportionierung der Benzhydrole und der alkalisch katalysierten Cannizzaro-Reaktion ein.

    Description / Table of Contents: Isolation and Structure of Larreagenin AFour glycosides have been isolated from leaves of the central american plant Larreu divaricata Cav.; the structure of one of the aglycons, larreagenin A, has been elucidated by means of 1H-NMR- and 13C-NMR-investigation together with other spectroscopic data as 3β-hydro-xy-29-nor-urs-13(18)-en-20β,28β-olide (4). Larreic acid, isolated from the same plant as glycoside, can be isomerized to larreagenin A.
