| titleOfInvention | Process for producing 3-substituted cephem compound |
| abstract | (57) [Summary] (Modified) [Objective] To provide a method for producing a 3-substituted cephem compound represented by the general formula (3) from an allenyl-β-lactam compound which can be easily produced from an inexpensive penicillin compound. To do. [Structure] The allenyl-β-lactam compound of the general formula (1) is prepared by applying 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 that of the metal. Metal compound having 0.0001-0. It comprises reacting with the organohalogen compound of the general formula (2) in the presence of a 5-fold molar amount. [Wherein R 1 represents a hydrogen atom, a halogen atom, a (protected) amino group; R 2 represents a hydrogen atom, a lower alkyl group, etc .; R 3 represents a hydrogen atom, a carboxylic acid protecting group; and R 4 represents phenyl. Group, pyridyl group and the like; R 5 represents a (substituted) 1-alkenyl group, a (substituted) aryl group; X represents a halogen atom] |
