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.

A one-pot, protecting-group-free benzannulation of 2-alkenylindoles with readily available 1,3-dicarbonyls is demonstrated to construct structurally diverse carbazoles. The use of a cheap Brønsted acid catalyst and air as the sole oxidant exemplifies the economic viability of this protocol. The execution of four different reactions successively to generate the medicinally important indolocarbazole

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.
