Hydrogenolysis of 16 using usual catalyst (absence or presence of acid) and reductive removal of a hydroxyl group with sodium borohydride in acetic acid were totally failed, only starting material was recovered. The replacement of a hydroxyl group of 16 to the corresponding halide and treatment of 16 with mesyl chloride or tosyl chloride in pyridine caused decomposition of the starting material.

As preliminary experiment, the oxidative demethylation of 16 employing cerium(IV) ammonium nitrate gave the quinone (29) in 52 % yield, and using argentic oxide in 39% yield (Y. Kitahara, S. Nakahara, Y. Koizumi, H. Muranishi, and A. Kubo, Chem. Pharm. Bull., 1988, 36, 3623).

MIC was determined by the agar (Difco) for fungi. In vitro activity of compounds (7 and 26) was determined from the size of inhibition zone using paper disk and T. mentagrophytes as test organism.
