Azetidinone intermediates to carbacephalosporins and process |
| abstract |
7β-Amino-3-hydroxy-1-carba(1-dethia)-3-cephem-4-carboxylic acid esters are provided via cyclization of cis-3-(substituted amino)-1-(2-substituted 2-oxoethyl)-4-substituted azetidinones. The 7β-amino-3-hydroxy-1-carba(1-dethia)-3-cephem-4-carboxylic acid esters are useful chiral intermediates to β-lactam antibiotics. |
