| titleOfInvention | The preparation method of steroidal ester |
| abstract | The invention discloses a preparation method of a steroidal esterification product. The alcoholic hydroxy steroidal compound (I) is used as a starting material, and through the catalysis of a catalyst, a dehydrating agent is used to undergo esterification with the alkanoic acid compound (II). Reaction, obtain steroidal ester compound (III), its operational route is as follows: Among them, R1 in the alcoholic hydroxysteroid compound (I) includes hydrogen, alkanes, enynes, and ketones; R2 in the alkanoic acid compound (II) includes C2-C18 alkanoic acids. The present invention can solve the problem of dehydration in the esterification reaction by using a combination of a novel dehydrating agent and a specific catalyst, making the reaction more moderate and sufficient, the operation more convenient, and the yield and quality greatly improved; at the same time, the dehydrating agent has no residual phenomenon. |
