摘要

Abstract

A series of 4-hydroxy-4,9-dihydro-4H-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-9H-xanthen-4(4aH)-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).
