PROCESS FOR PRODUCTION OF STEROID COMPOUND

摘要

Disclosed is a process for production of a steroid compound having a partial structure represented by the formula (2) by oxidizing a steroid compound having a partial structure represented by the formula (1), without the need of using any specialized apparatus, in a safe and economically advantageous manner, with less environmental load, in a simple manner and with high efficiency. Specifically, disclosed is a process for production of a steroid compound having a partial structure in each of ring A and ring B of the steroid skeleton represented by the formula (2), comprising reacting a steroid compound having a partial structure in each of ring A and ring B of the steroid skeleton represented by the formula (1) with a catalytic amount of a copper halide in the presence of an oxygen. wherein R represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms. wherein R is as defined in the formula (1) above.
