Divergent Synthesis of Pyrano[3,2-c]- and Furo[3,2-c]-carbazoles
A series of novel pyrano[3,2-c]- and furo[3,2-c]-carbazoles have been synthesized through diversity oriented synthesis, by adopting different methodologies using microwave condition and using different catalysts such as trifluoroacetic acid, ZnCl2/POCl3, P2O5/POCl3, triphenylphosphine by the efficient reaction of 4-hydroxy carbazole (1) with phenylpropiolic acid, dimethyl acrylic acid, malonic acid, cinnamic acid, dimethylacetylene dicarboxylate, ethylacetoacetate, malic acid and ethylcyanoacetate as suitable co-reactants.
