Synthesis

The desired derivatives 9–11 were all made from the common synthetic intermediate 2,7-dihydroxy-9-flfluorenone (12) (Scheme 1), which we prepared according to a modifification of the procedures reported by the groups of Andrews5 and Agrawal.6 9 was obtained by borohydride reduction of 12. Treatment of 12 with methyl iodide in basic DMSO gave the diether 13, which gave 10 on reduction with NaBH4. 11 was obtained by acetylation of 10 with acetic anhydride in pyridine.
