Abstract

Synthesis and Thermal Transformations of Pyrazolines Obtained by 1,3-Dipolar Addition of Diazocyclopropane to Maleimides. -The synthesis of spirocyclopropane-containing pyrazolines fused with a succinimide fragment and their thermolysis are described. This methodology is used for the preparation of novel polycyclopropane compounds, especially N-substituted monoamides of cis-spiropentane-1,2-dicarboxylic acids (VI) and (X), respectively. -(KOSTYUCHENKO, I.
