叔-丁基3,9-二氮杂双环[3.3.1]壬烷-9-羧酸盐

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of benzyl-3,9-diaza-bicyclo[3.3.1]nonane-9-carboxylic acid tert-butyl ester (477 mg, 1.51 mmol, 1.0 eq) and palladium hydroxide on carbon (466 mg) in ethanol (10 mL) was stirred with hydrogenation under balloon pressure until no more hydrogen uptake. The reaction was then filtered through celite and concentrated under reduced pressure. The crude was purified using chromatography (MeOH/Ethyl Acetate) which gave 3,9-Diaza-bicyclo[3.3.1]nonane-9-carboxylic acid tert-butyl ester (170 mg) in 47% yield. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.49 (s, 11H) 1.57-1.70 (m, 1H) 1.70-1.79 (m, 2H) 1.79-2.01 (m, 2H) 2.43-2.58 (m, J=19.14, 12.69, 6.32, 6.32 Hz, 1H) 2.93-3.05 (m, 2H) 3.05-3.18 (m, 2H) 3.99 (br. s., 1H) 4.11 (br. s., 1H) The reaction was then filtered through celite and concentrated under reduced pressure The crude was purified
