FIELD: chemistry.
SUBSTANCE: invention relates to a compound of formula (I-g) or a pharmaceutically acceptable salt thereof, where R1 chosen from (C1-C4 alkyl)-O, spirooxirane, cyano, =O, nitro, (C1-C4 alkyl)C(O) and HO(C1-C4 alkyl)C(O); R2 is H; R3 is H; Rb is methyl; R8 is H; - - - is an optional additional C-C bond providing a C=C bond between C16-C17, provided that, if present, R1 is not =O or spirooxirane. Invention also relates to individual compounds, a method for inducing anesthesia, to a method for treating disorders associated with the GABA function. 
.
EFFECT: technical result: obtaining novel compounds of formula (I-g), which can be useful in the treatment of disorders associated with the GABA function.
