170161-27-0, Tri-tert-butyl 1,4,8,11-tetraazacyclotetradecane-1,4,8-tricarboxylate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: The y-carbaldehyde intermediates (29.0 muL, 500 mumol) were added to a solution of tri-tert-butyl 1,4,8,11-tetraazacyclotetradecane-1,4,8-tricarboxylate (35.7 mg, 71.0 mumol) in MeOH (1.0 mL) and AcOH (100 L) under N2 and stirred for 2 h at room temperature. NaBH3CN (8.90 mg, 142 mumol) was added slowly to the reaction mixture and stirred at room temperature for 24 h. The reaction mixture was poured into saturated NaHCO3, extracted with EtOAc and dried with MgSO4. The organic layer was then washed with water and brine, dried with MgSO4 and concentrated under reduced pressure to obtain the corresponding tri-N-Boc-protected amine intermediates (68.9 mg), which were used in the next step without purification. The intermediates were then dissolved in CHCl3 (2.50 mL) and treated with 95% aqueous TFA (2.50 mL) at 0 C for 6 h. The mixture was concentrated under reduced pressure and purified by preparative HPLC to obtain the desired compounds 6-12.
