PTSA-promoted Robinson annelation of α-(3-oxobutyl)cyclohex-2-en-1-one derivatives in refluxing toluene, affords efficiently in a one pot process a variety of hydroxytetrahydronaphthyl carbonyl compounds in good yields. Further highly regioselective electrophilic bromination of these intermediates gave the corresponding bromide derivatives in 92–97% yield.

approach has been achieved for the cyclization of tetrahydronaphthalenes (THN) using α-bromoketones, resulting in the synthesis of benzo[]furans with high yields. The reaction occurred in DMF in the presence of KCO, operating at a temperature of 80 °C. The yields of this reaction range from 61 % to 93 %.
