Total synthesis1 of modified ellipticines and is described from 2-chloronicotinic acid and respectively 5-methoxy -indole and 5-azaindole in 11 to 13 steps with overall yields of 11% and 18%. With respect to the numerous synthesis described in the litterature, the originality of this approach resides above all in the formation of ring C in basic medium, such conditions being dictated by the presence
