Steroidal quinols were obtained on large scale in 50–70% yield, together with syn-epoxyquinols. The reaction conditions can be adjusted to afford only the corresponding steroidal epoxyquinol in 51–54% yield.

The preparation of A-ring steroidal 1,4-quinones involves m-CPBA/(BzO)2O/hv oxidation of estrone (or estradiol 17-acetate), acid rearrangement of the obtained quinol, and oxidation. A detailed NMR analysis of 1,4-quinones and their derivatives, as well as the results of preliminary antibacterial and cytotoxicity tests is presented.

was developed and used for oxidation of steroidal phenols to a quinol/epoxyquinol mixture. Reaction was optimized for estrone, by varying initiators (Fe-salts), reaction temperature, time and mode of MCPBA application. A series of five more substrates (17β-estradiol and its hydrophobized derivatives) was subjected to the optimized oxidation, providing corresponding p-quinols and 4β,5β-epoxyquinols in
