2,3,6,7-Tetramethoxyxanthen-9-one (7a): According to the General
Procedure F, a suspension of compound 10a (0.0506 g, 0.14 mmol)
in water (1.8 mL) was heated at 200 °C for 16 h. Purification by
radial chromatography (gradient, 30% EtOAc/hexanes to 60%
EtOAc/hexanes) yielded a white solid 7a (0.0375 g, 82%); m.p.
234.2–234.6 °C; Rf
=
0.45 (EtOAc/hexanes, 4:5). 1H NMR
