10534-59-5, Tetrabutylammonium acetate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a stirred solution of a tetrabutylammonium salt of (2S,5R)-N-{[1-tert-butoxycarbonyl (2R, 4S)-4-(morpholin-4-yl)pyrrolidin-2-ylj methoxy } -6-hydroxy-7-oxo- 1,6- diazabicyclo[3.2.ljoctane-2-carboxamide (1.5 g, 0.0032 mol) in dimethylformamide (15 ml) was added sulfur trioxide: dimethylformamide complex (1.0 g, 0.0064 mol) under stirring at temperature of about 0 C. The reaction mixture was stirred at 0 C for 10 minutes and then allowed to warm to 25C. After 1 hr of stirring a solution of tetra butyl ammonium acetate (2.89 g, 0.0096 mol) in water (8 ml) was added to the reaction mixture under continuous stirring. After completion of 1 hr stirring the solvent from the reaction mixture was evaporated under reduced pressure to obtain an oily residue. The residue obtained was then purified by silica gel(60-120 mesh size) column chromatography using 6% Methanol: DCM mixture as an eluant to get required compound. The solvent of the combined fractions were evaporated to provide 1.2 g of the titled compound as white solid, 47% yield. Analysis:Mass: 548.4 (M-1) as free acid; for Molecular weight: 791.07 and Molecular formula:C37H70N60 ftS?H NMR (CDC13, 400 MHz): 5 10.42 (brs, 1H), 4.38-4.28 (m, 1H), 3.98-3.92 (m, 1H), 3.86- 3.68 (m, 5H), 3.62-3.52 (m, 1H), 3.42-3.20 (m, 1OH), 2.98-2.84 (m, 2H), 2.58-2.32 (m, 5H), 2.24-2.14 (m, 1H), 1.96-1.84 (m, 2H), 1.84-1.62 (m, 12H), 1.56-1.42 (m, 17H), 1.06-0.97 (m, 12H).
10534-59-5, 10534-59-5 Tetrabutylammonium acetate 82707, acatalyst-ligand compound, is more and more widely used in various.
