A process for the production of a 2-azetidinone derivative. |
| 摘要 |
<p>A new and efficient process of producing a 2-azetidinone derivative is provided, which comprises cyclizing a beta -amino acid by treating with triphenylphosphine and a heterocyclic disulfide in the presence of an alkylnitrile. The 2-azetidinone derivatives produced are useful as starting compound for synthesis of beta -lactam group antibiotics such as thienamycin and nocardicin.</p> |
