The origin of a common compound about Ethyl quinuclidine-4-carboxylate

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand Ethyl quinuclidine-4-carboxylate reaction routes.

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.22766-68-3

To a solution of ethyl 1-aza-bicyclo[2.2.2]octane-4-carboxylate (PCT2005104745) (9.610 g, 52.44 mmol) in THF (480 ml) at -780C was added borane-THF complex (73.41 ml,73.41 mmol) and the resulting solution was stirred at this temperature for 3.5 h. The reaction was quenched with slow addition of H2O (50 ml), warmed to RT, and allowed to stir for 45 min. The solution was diluted with EtOAc (100 ml), washed with brine (15 ml), extracted with EtOAc (3 x 50 ml), dried (Na2SO4) and evaporated. The crude product was purified on a CombiFlash companion using 0-50% EtOAc in cyclohexane as eluent to give a bright yellow solid.Yield: 7.236 g (70%)1 H NMR (400 MHz, CDCI3) delta = 4.15 (q, 2H), 3.07 (t, 4H)1 1.96 (t, 4H), 1.26 (t, 3H) ppm.
