In the title molecule, C~21~H~26~O~2~, there are two C=C bonds [1.321โ (4) and 1.334โ (4)โ ร ], which contribute to the planarity of ring __A__ along with the carbonyl group. Rings __B__ and __C__ have regular chair conformations, while ring __D__ has an envelope conformation. In the crystal structure,
## Abstract The synthesis of radioactive androstaโ4,16โdienโ3โone from both 4โ[^14^C]โ and 7ฮฑโ[^3^ H]โtestosterone has been achieved using modifications of a method due to Henbest. Contrarily to this earlier report, yields of purified androstadienone were approximately 6%. Other compounds, which ma
