Reference of 3618-04-0, The chemical industry reduces the impact on the environment during synthesis 3618-04-0, name is trans-Ethyl 4-hydroxycyclohexanecarboxylate, I believe this compound will play a more active role in future production and life.
Step 1 : 4-(tert-Butyl-diphen l-silanyloxy)-cyclohexanecarboxylic acid ethyl esterTo a solution of ethyl 4-hydroxycyclohexane carboxylate (5.0 g, 29.03 mmol) in dichloromethane (200 mL) was added imidazole (4.97 g, 73 mmols) and tert- butylchlorodiphenylsilane (15.96 g, 15.2 mL, 58.0 mmol). The reaction mixture was allowed to stir at room temperature over night. The reaction mixture was poured into water (125 mL) in a separatory funnel and the phases were separated. The aqueous phase was extracted with dichloromethane (2×200 mL). The combined organic layers were washed with brine, dried over Na2SO4, and concentrated under vacuum. Purification by column chromatography on silica gel eluting with ethyl acetate in heptanes (0-10%) afforded 10.55 g (89%) of the title compound.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, trans-Ethyl 4-hydroxycyclohexanecarboxylate, other downstream synthetic routes, hurry up and to see.
