    Description / Table of Contents: Labelled Tropane Alkaloids, VI1). - Syntheses of [N-Methyl-T1] Psicain-neu and of Polytopically Tritiated PsicainThe reaction of norpsicain-neu (3) WITH cth2I yielded [N-methyl-T1] Psicain-neu (4), isolated as hydrochloride (activity 51.65 mCi/mmol). Polytopic tritiation of psicain (2) by a modified Wilzbach method yielded a product which was also isolated as hydrochloride with an activity of 30.8 mCi/mmol. The distribution of tritium in [3H]psicain in the benzoic acid, in the pseudoecgonine, and in the CH3O group was 84.5: 11.5:4 per cent.
    Notes: Durch Umsetzung von Norpsicain-neu (3) mit CTH2J wurde [N-Methyl-T1]Psicain-neu (4) dargestellt und als Hydrochlorid isoliert (Aktivität 51.65 mCi/mmol). Die polytope Tritiierung von Psicain (2) nach einer modifizierten Wilzbach-Methode ergab ein ebenfalls als Hydrochlorid isoliertes Produkt mit einer Aktivität von 30.8,Ci/mmol. Die prozentuale Verteilung des Tritiums im [3H]Psicain auf die Benzoesäure-, auf die Pseudoecgonin- und auf die CH3O- Gruppierungen betrug 84.5:11.5:4.

    Notes: Durch Einwirkung von KMnO4 in wäßr. Acetonitril erhält man: 1) Aus (-)-Cocain 23% d. Th. Nor-(-)-cocain sowie geringe Mengen des isomeren N-Benzoyl-nor-(-)-ekgoninmethylesters; 2) aus (+)-Pseudococain 51% d. Th. Nor-(+)-pseudococain; 3) aus O-Benzoyl-(+)-pseudoekgoninpropylester 56% d. Th. O-Benzoyl-nor-(+)-pseudoekgoninpropylester (Norpsicainneu); 4) aus Atropin 16% d. Th. α.β-Dihydroxy-α-phenyl-propionsäuretropylester (Atropin-7′-ol), der bei der Weiteroxydation Benzoesäure und CO2 gibt (Noratropin ist nicht nachweisbar); Atropin-7′-ol-N-oxid (7% d. Th.) bildet sich aus dem Alkohol mit Peroxid-haltigem Äther; 5) aus Tropacocain 57% d. Th. Nortropacocain.

    Description / Table of Contents: The Chemistry of Tropane Derivatives, VI1). - Substitution Products of Norpsicain and Norpsicain-neuReactions of norpsicain (1, R = H) and norpsicain-neu (2, R = H) with several mono- and α,ω-dihalogenides are described. Two homologue series 1 and 2 were synthesized in which R stands for ethyl, propyl, allyl, n-butyl, n-pentyl, n-hexyl, n-heptyl, n-octyl, n-nonyl, benzyl, and 2-phenylethyl, and two series 4 and 5 in which n can be 2, 3, 6, 7, and 8.
    Notes: Umsetzungen von Norpsicain (1, R = H) und Norpsicain-neu (2, R = H) mit Mono- und α,ω-Dihalogeniden werden beschrieben. Es wurden zwei homologe Reihen 1 und 2 dargestellt, bei denen R Äthyl, Propyl, Allyl, n-Butyl, n-Pentyl, n-Hexyl, n-Heptyl, n-Octyl, n-Nonyl, Benzyl und 2-Phenyläthyl ist, und die beiden Reihen 4 und 5, bei denen n den Werten 2, 3, 6, 7 und 8 entspricht.
