Abstract :
1-Methyl-3-(o-azidophenyl)quinoline-2-one prepared by cyclization of the corresponding o-vinylsubstituted isocyanate under microwave irradiation is directly converted into cryptotackieine 1 by an intramolecular aza-Wittig reaction with trimethylphosphine; alternatively heating followed by reduction of the resulting indoloquinoline derivative provided cryptosanguinolentine 2.
