17β-[[(Cyclohexylmethoxy)carbonyl]oxy]estra-4,9,11-trien-3-one - Reference Information
| introduction | trenbolone (Trenbolone,TRE) is a widely used steroid anabolic hormone, which is a chemically synthesized derivative similar to human male hormone testosterone in structure and activity. It can promote protein synthesis, increase appetite, increase muscle, and promote calcium and phosphorus in bone tissue. It can be used clinically to treat severe nutritional deficiencies and osteoporosis and other diseases, but it is also the most frequently used type of sports stimulant. Trenbolone cyclohexyl carbonate can be used as a synthetic intermediate of Trenbolone. |
| Preparation | Trenbolone cyclohexyl carbonate was prepared as follows: 3 g17/3-hydroxy-estradiol -4,9,11-triene -3-one was dissolved in pyridine at 15 ℃ under stirring and nitrogen atmosphere. Keep the temperature between 0 and 10 degrees Celsius. Slowly add 50ml hexahydrobenzyl chloroformate, then warm the entire mixture to ambient temperature, stir for 2 hours, and then cool to 0°C. Add triethylamine, stir for 30 minutes, raise the temperature to ambient temperature, and pour the reaction mixture into the water/ice mixture. It was extracted with dichloromethane, and the organic phase was washed with water to neutral, dried with sodium sulfate, and evaporated in vacuum to dryness. The residue was chromatographed on silica gel, eluted with a 4:1 benzene/ethyl acetate mixture, and the product was recrystallized from the isopropyl ether/hexane mixture. Chromatographic separation was performed again on silica gel, eluted with benzene/ethyl acetate ethyl acetate mixture, and finally recrystallized from cyclohexane and petroleum ether to obtain 1.60g of trenbolone cyclohexyl carbonate. The product appears in prismatic form soluble in ethanol, ether, benzene, acetone, and chloroform, but insoluble in water, dilute acid, and alkaline aqueous solutions. |
