| titleOfInvention | Method of preparing cephemic compounds or their salts |
| abstract | Usage: as antimicrobial agents in medicine. SUMMARY OF THE INVENTION: the product is cepheme compounds —C-CONH-T-A 0 NT CH2-R cov Ri © g A s -NAQR OR -c / -N: R4 N H J “P45-R Y where R is an amyl or protected amino group. pa, ZN or CH, C R2 is lower alkyl, lower alkenyl, carboxy (lower) alkyl or protected carboxy (lower) alkyl, R + is the group of R3 and R4 is lower cyclic or R3 + R4 alkylene; A is lower alkylene, R R and R are hydroxy or protected hydroxy; R is lower alkyl; Y-N or CH, or their salts. Reagent 1: 7-aminocephalosporin. Reagent 2: a-heterocyclyl-a-R-oxy-aminoacetic acid in the form of a mixed anhydride. Reaction conditions: in a solvent medium, followed by the possible removal of the protected groups and conversion to salt. 1 tab. ate with |
