The present invention relates to novel substituted indolo[2,3-a]quinolizines and stereoisomeric forms thereof and/or pharmaceutically acceptable salts of these compounds as well as pharmaceutical compositions containing at least one of these substituted indolo[2,3-a]quinolizines together with pharmaceutically acceptable carrier, excipient and/or diluents. Said novel substituted indolo[2,3-a]quinolizines have been identified as useful for the prophylaxis and treatment of cancer by the induction of strong mitotic delays, chromosomal misalignments and mitotic tri- and multipolarization leading to cell cycle stop and apoptosis. Furthermore a synthesis for preparation of the substituted indolo[2,3-a]quinolizines is disclosed in the present invention.

The present invention relates to novel substituted indolo [2,3-a] quinolizines of the general formula (I)
and stereoisomeric forms thereof and/or pharmaceutically acceptable salts of these compounds as well as pharmaceutical compositions containing at least one of these substituted indolo [2,3-a] quinolizines together with pharmaceutically acceptable carrier, excipient and/or diluents.

The imino Diels–Alderreaction is an efficient method for the synthesis of aza‐heterocycles. While different stereo‐ and enantioselective inverse‐electron‐demand imino Diels–Alder (IEDIDA) reactions have been reported before, IEDIDA reactions including electron‐deficient dienes are unprecedented. The first enantioselective IEDIDA reaction between electron‐poor chromone dienes and cyclic imines, catalyzed
