Synthesis, Structure, and Properties of 4-Hydroxy-4,9-dihydro-4H-xanthen-4-one Derivatieves

A series of 4-hydroxy-4,9-dihydro-4 H -xanthen-4-one derivatives were synthesized using the oxidative cyclization reaction of space-shielded catecholphenols. The structure of 1,3,5,7-tetra- tert -butyl-4a,8-dihydroxy-9 H -xanthen-4(4a H )-one was determined by X-ray diffraction analysis (CCDC 234589...

Summary:A series of 4-hydroxy-4,9-dihydro-4 H -xanthen-4-one derivatives were synthesized using the oxidative cyclization reaction of space-shielded catecholphenols. The structure of 1,3,5,7-tetra- tert -butyl-4a,8-dihydroxy-9 H -xanthen-4(4a H )-one was determined by X-ray diffraction analysis (CCDC 2345899). The antiradical properties of new compounds were studied by their reaction with 2,2-diphenyl-1-picrylhydrazyl (DPPH radical).
