Electric Literature 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.
EXAMPLE 5 5-Butyl-9-[1-(4,6-dimethyl-pyrimidine-5-carbonyl)-4-methyl-piperidin-4-yl]-3-(trans-4-hydroxy-cyclohexylmethyl)-1-oxa-3,9-diaza-spiro[5.5]undecan-2-one (I-4) 4-(tert-Butyl-dimethyl-silanyloxy)-cyclohexanecarboxylic acid ethyl ester (38)-To a solution of 4-oxy-cyclohexanecarboxylic acid ethyl ester (CASRN 17159-80-7, 1.7 g, 0.01 mol) in DMF (14 mL) was added DMAP (58 mg, 0.47 mmol), TEA (1.54 mL) and tert-butyl-dimethylsilyl chloride (1.65 g, 0.011 mol). The reaction mixture was stirred at RT for 18 h, poured into ice (10 g), extracted with EtOAc (3*50 mL). The organic extracts were dried (MgSO4) filtered and concentrated. The residue was purified by SiO2 chromatography eluding with EtOAc/hexane (1:20) to afford 2.25 g (79%) of 4-(tert-butyl-dimethyl-silanyloxy)-cyclohexanecarboxylic acid ethyl ester (38) as colorless oil.
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.
