As a common heterocyclic compound, it belongs to quinuclidine compound, name is Quinuclidine-4-carboxylic acid hydrochloride, and cas is 40117-63-3, its synthesis route is as follows.
Under the protection of nitrogen, phenyllithium (1.5 – 1.7M cyclohexane/diethyl ether solution (70:30), 30.0 ml, 48.00mmol) solution cooled to -30 C, in -30 C under, 0.5 hours slowly dropping WD2 (2.27g, 12 . 35mmol) of THF (30 ml) solution to the reaction mixture. The reaction liquid heating to room temperature reaction 16 hours, adding water quenching reaction, mixed solution under vacuum to evaporate to dry, adding water and ethyl acetate, to obtain white solid to settle out, filtering to obtain solid, shall WD1 (1.19g). The aqueous phase is further extracted with ethyl acetate, the combined organic layer was dried with anhydrous sodium sulfate, filtered, concentrated under reduced pressure to get the crude product, the crude product of ethyl acetate and hexane processing, filtering to obtain WD1.
40117-63-3, 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.,40117-63-3 ,Quinuclidine-4-carboxylic acid hydrochloride, other downstream synthetic routes, hurry up and to see
