Abstract

Novel steroids having the formula <FORM:1032267/C2/1> wherein R is hydrogen or lower alkyl containing 1-6 carbon atoms; R1 is hydrogen or lower carbalkoxy containing 2-6 carbon atoms; X is selected from the group consisting of -O- <FORM:1032267/C2/2> and <FORM:1032267/C2/3> is selected from the group consisting of <FORM:1032267/C2/4> are prepared by reacting a steroid of the formula: <FORM:1032267/C2/5> with a semicarbazide of the formula: <FORM:1032267/C2/6> wherein Y is S or O and R2 is H, lower alkyl (1-6 carbon atoms) or lower alkenyl (1-6 carbon atoms) in an inert solvent at 30-150 DEG C.
