| titleOfInvention | Process for producing (2R, 3S)-3-amino-1, 2-oxirane |
| abstract | A process for producing (2R, 3S)-3-amino-4-phenylbutane-1,2-epoxide compounds which comprises treating a (2S, 3S)-3-amino-1-halo-2-hydroxy-4-phenylbutane compound or a (2S, 3S)-3-amino-4-phenylbutane-1,2-epoxide with a carboxylic acid quaternary ammonium salt or a carboxylic acid metal salt a quaternary ammonium salt and a quaternary ammonium salt, to give a (2S, 3S)-1-acyloxy-3-amino-2-hydroxy-4-phenylbutane compound, further treating the same with a sulfonic acid halide in the presence of an organic base to give a (2S, 3S)-1-acyloxy-3-amino-2-sulfonyloxy-4-phenylbutane compound, furthermore treating said compound with an inorganic base. An intermediate for the production of an HIV protease inhibitor can be produced from L-phenylalanine. |
