    Description / Table of Contents: Reactions with Isocyanides.  -  Synthesis of Dispiro-1,3-dioxolanesThe synthesis of dispiro-1,3-dioxolanes, obtained from 2,3,4-trioxoquinolines and aromatic isocyanides, is described. The compounds 3a - e are formed via the dipolar intermediates 2a - e which add an additional molecule trioxoquinoline and subsequently undergoe cyclisation reaction. Their structures were elucidated from IR and MS data and, in the case of 3a, by an X-ray structure analysis.
    Notes: Es wird die Synthese von Dispiro-1,3-dioxolanen, erhalten aus 2,3,4-Trioxochinolinen und aromatischen Isocyaniden, beschrieben. Die Verbindungen 3a - e entstehen durch Cyclisierung der dipolaren Primäraddukte 2a - e mit einem weiteren Molekül Trioxochinolin. Die Strukturaufklärung erfolgt auf Grund von IR- und MS-Daten sowie einer Röntgenstrukturanalyse von 3a.
