Description / Table of Contents:
Unsymmetrically N-Substituted Bispidines (3,7-Diazabicyclo[3.3.1]nonanes), III1)The diastereoisomeric mixture 4 of 3,7-diazabicyclo[3.3.1]nonane-2,4,6,8-tetraones, in which the difference between the two aliphatic bridge substituents is sufficiently large, has been separated into the pure components. Their configurations have been determined by X-ray structural analysis of 4a. In the case of 5, where the two bridge substituents are very similar, the separation was not possible.
Notes:
Das Diastereomerengemisch 4 von 3,7-Diazabicyclo[3.3.1]nonan-2,4,6,8-tetraonen mit unterein-ander genügend verschiedenen aliphatischen Brückensubstituenten wird in die reinen Komponenten aufgetrennt. Die Konfigurationsbestimmung erfolgt durch Röntgenstrukturanalyse von 4a. Im Fall 5 mit sehr ähnlichen aliphatischen Brückensubstituenten gelingt die Trennung nicht mehr.
