2017, TetrahedronCitation Excerpt :8-Hydroxy-5H-dibenzo[c,f]chromen-5-one 120 has been prepared by the reaction of 1,3-dihydroxynaphthalene with 2-bromobenzoic acid in aqueous sodium hydroxide followed by neutralization with dilute HCl in poor yield (13%). A minor product has also been isolated in 0.6% yield and characterized as 11-hydroxy-6H-dibenzo[c,h]chromen-6-one130 117, Scheme 79. Numerous heterocycles have been synthesized either exploiting the functional groups present on the ring or through the ring transformation of pyran nucleus by various nucleophiles.
