| titleOfInvention | Production of 7-aminodesacetoxy-cephalosporanic acid esters thereof |
| abstract | PURPOSE: To obtain the titled compound as an intermediate for an antibacterial agent, by reacting esters of 7-acylamidedesacetoxycephalosporanic acid with an imino halide-forming agent in the presence of an aniline homologue, followed by reaction with a lower alcohol and hydrolysis thereof. n CONSTITUTION: Esters of 7-acylamidedesacetoxycephalosporanic acid expressed by formula I (R 1 represents phenyl-acetyl or pyhenyloxyacetyl; -COOR 2 represents esterified carboxyl) are reacted with an imino halide-forming agent (preferably phosphorus oxychloride, etc.) in an inert solvent (preferably methylene chloride, chloroform, etc.) in the presence of an aniline homologue (example; dimethylaniline, etc.). Then the product is reacted with a 1W7C alcohol and subjected to hydrolysis within an acidic region (example; pH=1) to give the aimed compound expressed by formula II. n COPYRIGHT: (C)1988,JPO&Japio |
