As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO372,mainly used in chemical industry, its synthesis route is as follows.,76176-87-9
To Intermediate 6 (2.77 g, 8.7 mmol, 1 eq), 1AI-thiomorpholin-1-one hydrochloride (1.62 g, 10.4 mmol, 1.2 eq) and NaOAc (853 mg, 10.4 mmol, 1.2eq) in anhydrous CH2CI2 (200 mL) was added NaBH(OAc)3 (2.94 g, 13.9 mmol,1 .6 eq). The reaction mixture was stirred at rt overnight. Then, it was partitioned with 1 N NaOH (50 mL) and H20 (50 mL), and extracted with CH2CI2 (3 x 20 mL). The combined organic extracts were dried over MgSO4, filtered and the solvent was removed in vacuo. Purification by silica gel column chromatography withEtOAc/MeOH (1:0-9:1), then CH2CI2/MeOH (1:0-4:1) yielded Intermediate 8 asa white solid (2.48 g, 68%).1H NMR (300MHz, DMSO-d5) oH. 8.62 (d, J=2.lHz, 1H), 8.51 (d, J=2.3Hz, 1H),4.00 (m, 4H), 3.74-3.84 (m, 6H), 2.83-3.00 (m, 4H), 2.61-2.81 (m, 4H).MS (ESj 422.1 (100%, [M+H]j.
With the synthetic route has been constantly updated, we look forward to future research findings about Thiomorpholine-1-oxide hydrochloride,belong Thiomorpholine compound
