Xanthone, as its dimethyl ketal, undergoes functionalization with a synthetically useful degree of regioselectivity using a lithiation protocol. The core structure is regenerated during the work-up. Monosubstitution at C-4 or C-1 and disubstitution at C-4 and C-5 OF C-1 and C-5 are observed. The substitution pattern appears to be dependent upon the experimental conditions. (C) 2009 Elsevier Ltd.
