This book was released on 1987 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les iodures de N-dimêthyl hexahydro-1H-benzazoninium-2 en présence d'amidure de sodium dans l'ammoniac 1iquide, conduisent à des aza-2 (7) métacyclophanes par transposition de Sommelet-Hauser. Les iodures de N-diméthyl hexahydro benzazocinium-2 donnent régiosélectivement et stéréospécif1quement des énamines. Nous avons soumis aux mêmes conditions réactionnelles, les iodures de N-diméthyl hexahydro thiéno (3,2-c) et (2,3-c) azocinium ainsi que les halogénures de N-alkyl N-méthyl hexahydro 4H thiéno (3,2-c) et (2,3-c) azocinium. Ces sels conduisent à des composés spiranniques ayant perdu leur aromaticité selon un réarrangement sigmatropique (2,3) hautement diastéréosélectif et â des amines éthyléniques provenant d'élimination d'HOFMANN. Les sels de N-(allyl, benzyl et thényl) N-méthyl hexahydro 4H thiéno (3, 2-c) azoninium se décomposent régiosélectivement en thiéno (3, 2-d) azécines par une réaction de STEVENS. L'étude en Résonance Magnétique Nucléa ire de ces àzécines montre que tous les protons sont différenciés, elle a permis d'établir la conformation d'un fragment structural de ces molécules. Une conformation moyenne en solution a été proposée pour les sels de thiéno (3,2-c) azoninium.

Download or read book Progress in Chemical Toxicology written by Abraham Stolman and published by Elsevier. This book was released on 2013-10-22 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in Chemical Toxicology, Volume 5 covers topics on the improved isolation and detection procedures and quantitation methods for volatile poisons, stimulants, hallucinogenic drugs, and marihuana. The book discusses the absorption, distribution, and excretion of drugs and poisons and their metabolites; the system for the toxicological analysis of drugs in biological specimens; and the isolation and analysis of phenothiazines. The text also describes the use of fluorescence in toxicology and the toxicology of new synthetic organic polymers used in containers for food, pharmaceutical compounds, and drinkable water. Some microcrystal tests for drugs and advances in polarography as applied to toxicological analysis are also considered. Biochemists, toxicologists, and scientists involved in the study of narcotics will find the book invaluable.
