  • (4S)-1-(tert-Butyloxycarbonyl)-4-[N,N'-Bis(tert-Butyl-oxycarbonyl)guanidino]-L-Proline tert-Butyl Ester [ No CAS ]
YieldReaction ConditionsOperation in experiment
60.2 mg (24%) In N,N-dimethyl-formamide; Step C (4S)-1-(tert-Butyloxycarbonyl)-4-[N,N'-Bis(tert-Butyl-oxycarbonyl)guanidino]-L-Proline tert-Butyl Ester A solution of (4R)-1-(tert-butyloxycarbonyl)-4-amino-L-proline tert-butyl ester (134 mg, 0.468 mmol) and N,N'-bis(tert-butyloxycarbonyl)-S-methyl-isothiourea (150 mg, 0.515 mmol) in N,N-dimethylformamide (2 mL) was heated for 15 hours at 55° C. and 2 days at room temperature under a nitrogen atmosphere. The reaction mixture was diluted with diethyl ether, washed with water, dried (Na2 SO4), and evaporated. The title compound was obtained pure by flash silica gel chromatography eluding with 10percent ethyl acetate/hexane; yield 60.2 mg (24percent). Mass spectrum: m/z 529 (M+1); 400 MHz 1 H NMR (CD3 OD): delta1.44-1.52 (4s, 36H); 2.08 (m, 1H); 2.59 (m, 1H); 3.42 (m, 1H); 3.78 (m, 1H); 4.23 (dd, 1H); 4.57 (m, 1H).

YieldReaction ConditionsOperation in experiment
114 mg (36%) In tetrahydrofuran; water; Step F (4R)-1-(tert-Butyloxycarbonyl)-4-[N,N'-Bis(tert-Butyloxycarbonyl)guanidino]-L-Proline tert-Butyl Ester A solution of (4R)-1-(tert-butyloxycarbonyl)-4-amino-L-proline tert-butyl ester (172 mg, 0.600 mmol) and N,N'-bis(tert-butyloxycarbonyl)-S-methyl-isothiourea (192 mg, 0.661 mmol) in tetrahydrofuran (3.5 mL) and water (70 muL) was heated for 18 hours at 55° C. and 1 day at room temperature under a nitrogen atmosphere. The reaction mixture was evaporated, and the title compound was obtained pure by flash silica gel chromatography eluding with 15percent ethyl acetate/hexane; yield 114 mg (36percent). Mass spectrum: m/z 529 (M+1); 400 MHz 1 H NMR (CD3 OD): delta1.44-1.52 (36H); 2.20-2.39 (m, 2H); 3.39 (m, 1H); 3.74 (dd, 1H); 4.13 (m, 1H).
