Convenient method for the functionalization of the 4- and 6-positions of the androgen skeleton

The preparation and reactivity of steroidal vinyldiazo compounds is reported, providing a convenient, substituent tolerant, chemo- and stereoselective entry into 4- and 6-substituted androgen analogues from a common precursor. Under dirhodium catalysis, O-H insertion occurs at the carbenoid site, leading to 4-substituted steroids, but under silver catalysis, O-H insertion occurs at the vinylogous position, leading to 6-substituted steroids.

SUBSTITUTED ANDROST-4-ENE DIONES

The disclosure relates to novel C4 and C6 substituted androst-4-ene diones as well as andros-1,4-diene diones and derivatives thereof, their process of preparation, pharmaceutical compounds containing them, and the use of said compounds for the treatment of hormone-related disorders in mammals. This includes hormone-dependent cancers, particularly those caused by elevated levels of estrogen and its intermediates. These compounds can also be used in the treatment of other hormone-related disorders, inluding benign prostatic hyperplasia, cardiovascular disease, and neurodegenerative disorders.
