Preparation of β-lactam Compound |
| abstract |
A process for producing an allenyl β-lactam compound represented by the formula (II) or a 3-halosefem compound represented by the formula (III) by using a halogenated β-lactam compound represented by the formula (I) as a starting material and changing the reaction conditions.n n n Formula In n n n n n n n (Wherein R 1 represents a hydrogen atom, an amino group or a protected amino group, and R 2 represents an optionally substituted aryl group. N represents 0 to 2. R 3 represents a hydrogen atom or a carboxylic acid protecting group.) Is a halogen atom, Y is a halogen atom or a leaving group.)n n n Formula IIn n n n n n n n Wherein R 1 , R 2 , n and R 3 are as defined above.n n n Formula IIIn n n n n n n n (Wherein R 1 , R 3 and X are the same as above). |
