Abstract
A simple and inexpensive oxidative photocyclization of the bisindolylmaleimides in the presence of a catalytic amount of iodine leading to indolo[2,3-a]pyrrolo[3,4-c]carbazoles in 84-90% yields is described.
Key words
photooxidation - indole alkaloid - heterocycle - staurosporine - aglycon
