We describe here the synthesis of 1,2‐dimethyl‐phenanthro [1,2‐ b ] furan ( 11 ) and 1‐ethyl‐2‐methyl‐phenanthro [1,2‐ b ] furan ( 13 ). The starting material was the known ethyl 2‐methyl‐phenanthro [1,2‐ b ] furan‐1‐carboxylate ( 4 ). The two synthetized substances were characterized by their UV.‐, IR.‐, NMR.‐ and mass spectra, and identified with two products obtained by selenium dehydrogenation of anhydrohirundigenin.
