Synthesis of beta-lactams from azetidine carboxylic acid esters |
| abstract |
Azetidine carboxylic acid esters are converted into enol silyl ethers which, as enamino ketene acetals, undergo ready oxidative cleavage of the ethylenically unsaturated double bond, e.g. by dye-sensitized photo-oxygenation, to form beta-lactams. The beta-lactams and substitution products thereof are useful intermediates in the synthesis of biologically active lactams. |
