Synthesis of indolocarbazoles was achieved through thermal electrocyclization followed by triethyl phosphite-mediated nitrene insertion reactions. Total synthesis of staurosporinoneanalogues was achieved from commercially available 2-methylindole. The CDK5/p25 kinase inhibition potential of some representative staurosporinoneanalogues was explored by using the TRFRET kinase assay.

Interaction of 2/(3)-methyl-3/(2)-vinylindoles and DMF center dot DMA/DMA center dot DMA at 110 degrees C led to the in situ generation of enamines, which on concurrent electrocyclization followed by subsequent aromatization afforded substituted carbazoles.

A synthesis of staurosporine aglycon and its analogs was achieved in a 28−36% overall yield starting from 2-methylindole. The prominent key steps for the synthesis of the indolocarbazole alkaloids involved electrocyclization and nitrene insertion reactions.
