Abstract: Abstract The first derivative of a novel heterocyclic system, (7 E ,10a E )-2,7-dimethylfuro[3′,4′:6,7]-cycloocta[1,2,3- cd ]indole-8,10(2 H ,6 H )-dione, was synthesized based on the Stobbe condensation of 3-chloro-1-methylindole-2-carbaldehyde with diethyl isopropylidenesuccinate. Cyclization of the… read more here.
