The spiro[cyclohexane-1,2′-[2H]indene] derivatives 15a,b with molecular dimensions and nucleophilic functional groups similar to known steroid 5α-reductaseinhibitors (e.g.2) were synthesized. The spiro[cyclohexane-1,2′-[2H]indene]-1′(3′H),4-dione (5) was synthesized from 5-methoxyindan-l-one ( = 2,3-dihydro-5-methoxy-1H-inden-1-one). A Grignard reaction and a dehydration step led to the cyclohexene
