Route of Synthesis (ROS)
| Conditions | Yield |
| With sodium hydrogencarbonate In water; acetone at 40℃; for 1h; Experimental Procedure General procedure: Samples of each 0.4 mg of 1 and 2 were hydrolyzed by heating in 1 ml 6 N HCl for 24 h at 110 °C. After cooling, the solution was evaporated to dryness and the residue redissolved in H2O (50 μL). To each of these hydrolyzate solutions, or to a solution of the reference amino acid (50 μL; 50 mM), a solution of FDAA (Marfey’s reagent, N-(2,4-dinitro-5-fluorophenyl)-l-alaninamide) in acetone (100 μL of 1% (w/v) solution) was added. After addition of NaHCO3 solution (20 μL; 1 M), the mixture was incubated for 1 h at 40 °C. The reaction was stopped by addition of HCl (10 μL; 2 M), the solvents were evaporated, and the residue was redissolved in acetonitrile (1 ml). An aliquot of this solution (20 μL) was analyzed by HPLC (Phenomenex Luna C18, 250 4.6 mm, 5 μm; solvents: A is H2O + 0.05% HCOOH, B is MeOH + 0.05% HCOOH; linear gradient from 10% B in A at t = 0 min to 90% B in A within 20 min; 25 °C; 300 μL min-1). Configuration of the amino acid units were determined by comparing the chromatograms with those of derivatives of commercially available amino acids. The retention times (min) were as follows: l-Val (15.1), d-Val (16.9), N-Me-l-Val (16.0), N-Me-d-Val (17.0), l-Phe (16.4), d-Phe (18.1), N-Me-l-Phe (15.9), and N-Me-d-Phe (11.6). 26 In independent experiments, all 1/2-derived amino acids were shown to have the l-configuration. | |
