68% With sulfuric acid; sodium nitrite In water at 0 - 20℃; (R)-2-Amino-3-phenylpropionic acid (5.3 g, 32 mmol) was placed into a three- necked flask, and water (24 mL) was added. The flask was fitted with two addition funnels. 2N H2SO4 (18 mL) was placed in one addition funnel and 2N aqueous NaNO2 (18 mL) was placed in the other one. The reaction vessel was cooled to 0°C, and the acid was added dropwise with stirring. After the initial amino acid was dissolved, dropwise addition of the NaNO2 solution started. Upon completion of the addition, the reaction was stirred at 0°C for 3 hours and then allowed to stir at room temperature for 2 days. Then the reaction mixture was extracted several times with ethyl acetate. The combined organic layers were dried, filtered and concentrated under reduced pressure to give E51 (3.6 g, 68% yield) as a white solid.

Chem., 23, 666) Following the procedure of Johnson, 1980, D-phenylalanine (16.5 g, 100 mmol) was dissolved in 1N H2 SO4 (150 ml) and cooled to 0° C. A solution of NaNO2 (10.5 g, 150 mmol) in water (50 ml) was added dropwise. The mixture was stirred for 2 h at 0° C. and for 3 h at 25° C. The product was extracted into ether (5*100 ml) and the combined ether extracts were dried over Na2 SO4 and concentrated in vacuo to about 100 ml. Hexane (300 ml) was added and the product which crystallized out was collected by vacuum filtration to afford the title compound as a colorless solid (9 g, 54%); mp=124°-125° C.

With sulfuric acid; sodium nitrite In water at 20℃; for 27h; Cooling with ice; 1. 4.1 D-α-hydroxy acid 10(A-C, G) General procedure: A 60 ml of aqueous solution of sodium nitrite (20.7 g, 0.3 mol) was added into a stirred and ice-cooled solution of D-amino acids (9A-C, G, 50 mmol) in 1 M H2SO4 (100 ml, 0.1 mol) over 3 h, and the mixture was stirred for 24 h at room temperature until the completion of the reaction (monitored by ninhydrin). The mixture was adjusted to pH 6 with solid NaHCO3 and then to pH 3 with concentrated HCl followed by freeze-drying. The resulting residue was extracted with hot acetone (4×100 ml), and the extracts were concentrated and dried to offer colorless oil, to which ether (200 ml) was added and filtrated to remove insoluble solids, the filtrate was concentrated and re-crystallized in ether/hexanes mixture to afford 10(A-C, G) as white crystalline, yield 82%-92%.
