Sources of common compounds: 22766-68-3

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. 22766-68-3, other downstream synthetic routes, hurry up and to see.

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.22766-68-3,Ethyl quinuclidine-4-carboxylate, it is a common compound, a new synthetic route is introduced below.

Step 1. A solution of 4-carbethoxyquinuclidine (10.92 g) in THF (155 mL) was treated at-780C with borane-THF (1.0 M, 77.5 mL). The resulting mixture was stirred at -78C for 4 h, then treated with water (50 mL), warmed to room temperature and stirred for an additional hour. The reaction mixture was diluted with ethyl acetate and the aqueous phase was separated and extracted with two further portions of ethyl acetate. The combined organic layers were washed with brine- (twice), dried (MgSO4), filtered and evaporated in vacuo. Purification by silica gel chromatography (eluting with cyclohexane-ethyl acetate [1 :0 to 1 :1]) gave 1-boranyl-1-aza-bicyclo[2.2.2]octane-4- carboxylic acid ethyl ester (7.12 g, 61%) as an off-white solid. 1H NMR (400 MHz, CDCI3) delta 4.16 (2H1 q, J = 6.9), 3.10-3.05 (6H1 m), 1.98-1.93 (6H, m), 1.26 (3H, t, J = 6.9).
