| titleOfInvention | Process for producing 3-halogenated cephem derivative |
| abstract | (57) [Summary] (Modified) [Objective] A general-purpose production method capable of producing the desired 3-halogenated cephem derivative with high yield and high purity by overcoming the drawbacks found in the conventional production methods. I will provide a. [Structure] The compound represented by the general formula (2) is obtained by reacting an allenyl β-lactam compound represented by the general formula (1) with a halogenating agent in the presence of a sulfinate ion or thiolate ion scavenger. To produce a 3-halogenated cephem derivative. [Wherein R 1 represents a hydrogen atom, an amino group or a protected amino group, R 2 represents a hydrogen atom, a halogen atom, a lower alkoxy group, a lower acyl group, or a lower alkyl having a hydroxyl group or a protected hydroxyl group as a substituent. Group, R 3 represents a hydrogen atom or a carboxylic acid protecting group, R 4 represents an aromatic compound residue or a nitrogen-containing aromatic heterocyclic compound residue which may have a substituent, and X represents a halogen atom. . n is 0 ~ 2 is shown. ] |
