Steroidal imidazole 1 carboxylic acid esters

A variety of steroidal esters of imidazole 1 carboxylic acid and related acids was prepared by reaction of the steroidal alcohol with N,N' carbonyldiimidazole or by displacement of phenol from steroid phenylcarbonates. One compound, 21c (the imidazole 1 carboxylate of 19 norethisterone), was found to have an interesting separation of progestational from androgenic activity.
