22766-68-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Ethyl quinuclidine-4-carboxylate, cas is 22766-68-3,the quinuclidine compound, it is a common compound, a new synthetic route is introduced below.
Example 33 Preparation of 1-azabicyclo[2.2.2]oct-4-yl(di-3-thienyl)methanol A solution of t-Butyl lithium (1.7M in pentanes, 5.8 mL, 9.86 mmol) was chilled to -78 C. under Ar. 3-Bromothiophene (0.46 mL, 4.90 mmol) dissolved in THF (4.0 mL) was slowly added to the reaction mixture over 6 min. The reaction was stirred for 30 min and then ethyl 1-azabicyclo[2.2.2]octane-4-carboxylate (0.3132 g, 1.71 mmol) in THF (4 mL) was added. The reaction was allowed to warm up from -78 C. to room temperature over 16 h. After 14 hours, the reaction was slowly quenched with water. EtOAc was added, causing a grey solid to crash out. The solid was filtered off to give the title compound (0.3375 g, 64.6%). EI-MS m/z 306(M+H)+ Rt (1.27 min).
The chemical industry reduces the impact on the environment during synthesis,22766-68-3,Ethyl quinuclidine-4-carboxylate,I believe this compound will play a more active role in future production and life.
