Abstract (2. Language): 
Two benzocoumarins and a benzochromone were synthesized starting from 2,7-dihydroxynaphthalene (2,7-DHN) and ethyl acetoacetate (EAA) in the presence of sulphuric acid solutions as condensing agent. The structures of the products have been elucidated by 1H NMR, 13C NMR, IR and Mass spectral methods. Increasing concentration of H2SO4 promotes the yield of benzochromone 3 is the most important observation.

İki benzokumarin ve bir benzokromon, kondensazyon aracı olarak sülfürik asid çözeltisi varlığında 2,7-dihidroksinaftalin ve etil asetoasetat (EAA)’ tan başlayarak sentezlendi. Bu bileşiklerin yapıları 1H NMR, 13C NMR, IR ve Kütle spektral metodlarla açıklandı. Artan H2SO4 konsantrasyonu en önemli gözlem olan benzokromonun 3 verimini arttırır.
