| titleOfInvention | Process for producing optically pure 3-hydroxy-pyrrolidine |
| abstract | The present invention relates to a method for preparing optically pure 3-hydroxy-pyrrolidine, and more particularly, to react with ammonia and an aldehyde compound using 3,4-epoxy-1-butanol having optical activity as a starting material. After preparing the 4-protected imino-butane-1,3-diol, the hydroxy group at the C-1 position is selectively activated, or subsequently treated with an acid to convert the imino group into an amine group, and then in the presence of a base. By carrying out an intramolecular cyclization reaction, it relates to a novel process for producing 3-hydroxy-pyrrolidine represented by the following formula (1) economically and simply in high yield optically.n n n n n n n n n n In Chemical Formula 1, * represents a compound (S) or (R) having optical activity. |
