Abstract
The different base-promoted regioselectivities of the ring closure processes in the reactions between cycloalkenyl-1-diazenes and β-ketoesters are investigated. Under the appropriate conditions it is possible to turn the synthesis towards cycloalkenyliden-pyrroles or functionalized 3-hydroxy-hydrocinnolines. The aromatization procedure of the heteroring counterpart of the 3-hydroxy-hydrocinnolines is also reported.
