| titleOfInvention | A PROCEDURE FOR THE PRODUCTION OF A 7-AMINO ACID (REPLACED) -3- (REPLACED THYMETIL) D3-CEFEM-4-CARBOXYLIC. |
| abstract | A process for the production of a 7- amino (substituted) -3- (substituted tomato) -delta3-cephea-4-carboxylic acid represented by the general formula: ** (Formula-01) ** where R1 is an atom of hydrogen or a C1-4 alkoxy group; R2 is an amino group or a group represented by the formula ** (Formula-02) **, where R3, R4 and R5, which may be the same or different, are hydrogen atoms or organic residues that do not participate in the reaction, or by the formula ** (Formula-03) **, where R6 and R7, which may be the same or different, are hydrogen atoms or organic residues that do not participate in the reaction; and R8 is a residue of a thiolytic compound; or a derivative on the carboxyl group thereof or a salt thereof; which process consists of reacting a cephalosporanic acid represented by the general formula; ** (Formula-04) ** where R1 and R2 have the meaning given above; X is a substituted or unsubstituted acyloxy or carbamoixoli group; ** (Formula-05) **, or a derivative in the carboxyl group thereof or a salt thereof, with a thiol represented by the general formula R8-SH (III) where R8 is the one defined above, or a salt thereof , in an organic solvent and in the presence of a protonic acid, a Lewis acid other than boron trifluoride and its complex compounds. |
