- Lipase originating from Sephacia (Amano Lipase PS (trade name); manufactured by Aldrich) 5.00 g was added and stirred at room temperature. After 30 minutes, the filtrate obtained by filtration under reduced pressure was lyophilized to obtain 1.50 g of lipase chemically treated as a green powder.
- the (R) -3-amino-3-ethylpropionic acid ethyl ester is converted into the (R) -3- (2-furamino) 3-phenylpropionic acid ethyl ester by a conventional method to produce optical activity.
- the optical purity was measured using high performance liquid chromatography using a neutral column and found to be 95.7% ee.
- Ethanolol 250mU, 4 Trinoleanolide 50. Og (0.42mol), Malonic acid 47.6g (0.46mol) and Ammonium acetate 64.2g (0.83mol) were added under reflux with stirring (8 The reaction was performed at 0 to 90 ° C for 7.5 hours. The resulting reaction solution was stirred at 0-5 ° C for 30 minutes and then filtered to obtain 51.4 g of 3-amino-3- (4-tolyl) propionic acid (racemic mixture) as a white powder (4 Isolated yield based on tolylaldehyde: 68.9%).
- optical purity of (S) -3-amino-3- (4-tolyl) propionic acid measured by high performance liquid chromatography using an optically active column was 99.8% ee.
- Optically active 3 (2 furoamino)-3- (4 tolyl) propionic acid ethyl ester
- the present invention relates to a method for simultaneously obtaining optically active (S or R) - ⁇ -amino acid and optically active (R or S) - ⁇ -amino acid ester from ⁇ -amino acid ester (racemic mixture).
- optically active j8-amino acids and esters thereof are useful as raw materials or synthetic intermediates for physiologically active peptides and ratata based antibiotics.
