As a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, name is (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine, and cas is 31886-58-5, its synthesis route is as follows.
(S)-Ugi-amine 1 (5.14g, 20mmol) was dissolved in 50mL of diethyl ether. Under nitrogen and ice salt bath cooling, n-butyl lithium (16mL, 2.5mol / L) was added dropwise to the reaction system, After the completion, the temperature was slowly raised to room temperature, and the reaction was stirred for 3 hours. Chlorodiphenylphosphine (8.82 g, 40 mmol) was added dropwise under ice-cooling, and the mixture was slowly warmed to room temperature and stirred for 12 hours. The reaction was quenched with saturated sodium bicarbonate solution. Extracted with dichloromethane, dried over anhydrous sodium sulfate, concentration, column chromatography to obtain compound 2 (5.38g, 61%).
31886-58-5, 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.,31886-58-5 ,(R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine, other downstream synthetic routes, hurry up and to see
