| titleOfInvention | Method for producing 2-isosephem derivative |
| abstract | (57) [Summary] (Modified) [Objective] To provide a novel method for producing a cephem derivative which synthesizes a 3-halomethyl-2-isocephem derivative or a 3-halomethyl-2-oxaisosephem derivative in one step. [Structure] 2-azetidinyl-represented by the general formula (1) A compound represented by the general formula (2), which comprises reacting a 3,4-dihalogeno-2-butenoic acid compound with a thioacetic acid derivative which itself is basic or a mixture of a base and a thioacetic acid derivative in a water-containing organic solvent. Method for producing 3-halomethyl-2-isocephem derivative, and said 2-azetidinyl- A compound represented by the formula (3), which comprises reacting a 3,4-dihalogeno-2-butenoic acid compound with a base in a water-containing organic solvent. A method for producing a 3-halomethyl-2-oxaisocephem derivative represented by: [Wherein R 1 is a hydrogen atom or a (protected) amino group; R 2 is a hydrogen atom or a lower alkoxy group; R 3 is a hydrogen atom or a carboxylic acid protecting group; W is a leaving group; X, Y Are halogen atoms; ] |
