    Description / Table of Contents: Zusammenfassung Der Umsatz von Xanthobilirubinsäuremethylester mit Brom in Methanol ergibt in 20-prozentiger Ausbeute ein rotes Pigment, für das die bislang nicht bekannte 16,24-Dehydrobiladien-ab-Konstitution abgeleitet wurde. Darüber hinaus konnte das entsprechende Mesobiliverdin-XIIIα, Mesobilirubin-XIIIα, 14-Formyltripyrrinon, und zwei diastereomere 15,16-Dimethoxybiladiene-ab aus der Reaktionsmischung isoliert werden. Die mechanistischen Aspekte dieser Reaktion werden diskutiert.
    Notes: Summary On treating xanthobilirubic acid methyl ester with bromine in methanol, a red bile pigment, which was assigned the hitherto unknown 16,24-dehydrobiladiene-ab constitution, is obtained in 20% yield. In addition, the corresponding mesobiliverdin-XIIIα, mesobilirubin-XIIIα, 14-formyl-tripyrrinone, and two diastereomeric 15,16-dimethoxybiladienes-ab could be isolated from the reaction mixture. The mechanistic aspects of this reaction are discussed.

    Notes: Abstract 2,4,6-Triaminotoluene (TAT), an oxygen sensitive metabolic product of 2,4,6-trinitrotoluene (TNT) reduction, was derivatized yielding oxygen stable products using a procedure previously employed for the stabilization of other O2sensitive TNT metabolic products. A HPLC method is presented that allows for the separation of diverse intermediates and products of TNT metabolism following the derivatization procedure. © Rapid Science Ltd. 1998
