| titleOfInvention | Process for producing 17β- (substituted) -3-oxo-Δ1,2-4-azasteroids and intermediates |
| abstract | OR 2 where R 1 is C 1 -C 4 alkyl and R 2 is a C 1 -C 4 alkyl radical, or R 3 and R 4 are equal or different, hydrogen or C 1 -C 4 alkyl to a radical, 17.beta. (substituted) -3-oxo - [delta 1, 2-4-aza-steroids (I) are 2- (substituted) of formula (IV) R 5 is Br or trichloromethyl sulfonyl -3 -It can be obtained by a method comprising the step of cleaving the oxazolidinedione ring present in hydroxyoxazolidinedione and removing the substituent at the 2-position to form a double bond at the 1,2-position. A part of compound (I) is a testosterone-5α-reductase inhibitor and can be used for the treatment of hyperandrogenic diseases. [Chemical 1] |
