Okuma, Kentaro published the artcileReaction of Benzyne with Salicylaldehydes: General Synthesis of Xanthenes, Xanthones, and Xanthols, Category: alcohols-buliding-blocks, the publication is Organic Letters (2009), 11(1), 169-171, database is CAplus and MEDLINE.
The reaction of salicylaldehydes with benzyne prepared from o-trimethylsilylphenyl triflate and CsF gave xanthenes and xanthones. When the reaction was carried out under basic conditions, 9-hydroxyxanthenes (xanthols) were obtained in good yields.
Organic Letters published new progress about 596-38-3. 596-38-3 belongs to alcohols-buliding-blocks, auxiliary class Other Aromatic Heterocyclic,Benzene,Alcohol, name is 9-Phenyl-9H-xanthen-9-ol, and the molecular formula is C19H14O2, Category: alcohols-buliding-blocks.
