titleOfInvention | Process for producing exo-methylenepenam compounds |
abstract | The cefem compound represented by Formula 1 is reduced by a 0.0001 to 30-fold molar amount of a metal compound having at least an equimolar amount of a metal having a standard redox potential of -0.3 (V / SCE) or less and a standard redox potential higher than the metal. A method for producing an exomethylenephenam compound, characterized by obtaining an exomethylenephenam compound represented by the formula (2).n n n (Formula 1)n n n n n n n n [Wherein, R 1 represents a hydrogen atom, an amino group or a protected amino group. R < 2> represents a hydrogen atom, a halogen atom, etc. R 3 represents a hydrogen atom or a carboxylic acid protecting group. X represents a halogen atom or the like]n n n (Formula 2)n n n n n n n n [Wherein R 1 , R 2 and R 3 are the same as above] |
