It can promote protein synthesis, appetite, muscle growth, promote calcium and phosphorus in bone tissue calm, clinical can be used to treat serious nutritional deficiency and osteoporosis and other diseases, but it is also the most frequently used sports stimulant. Cyclohexyl carbonic acid can be used as synthesis intermediate of cyclohexyl carbonic acid. Preparation of group blon cyclohexyl carbonate preparation is as follows: in the stirred and nitrogen atmosphere, at 15℃, at 0℃ 3G17/3-hydroxy-estradiol-4,9, 11-triene-3-one dissolved in pyridine. Keep the temperature between 0 and 10 degrees Celsius. Slowly add 50ml hexahydrobenzyl chloroformate, then warm the whole mixture to ambient temperature, stir for 2 hours, then cool to 0 ° C. Add triethylamine, stir for 30 minutes to bring the temperature to ambient temperature, and pour the reaction mixture into the water/ice mixture. It was extracted with methylene chloride, and the organic phase was washed with water to neutral, dried with sodium sulfate, and vacuum evaporated to dry. The residue was chromatographically separated on silica gel, eluted with a 4:1 mixture of benzene/ethyl acetate, and recrystallized from the isopropyl ether/hexane mixture. Chromatographic separation was carried out again on silica gel, elution was performed with benzene/ethyl acetate ethyl acetate mixture, and finally recrystallized from cyclohexane and petroleum ether to obtain 1.60g group boroncyclohexyl carbonate. The product occurs in prismatic form soluble in ethanol, ether, benzene, acetone and chloroform, but insoluble in water, dilute acid and alkaline water solutions.
