beta -Lactams, their production, intermediates thereto and derivatives thereof |
摘要 |
gamma -lactones are converted into both known and new azetidine carboxylic acids which can be transformed readily to the corresponding beta -lactams by oxidative decarboxylation. The beta -lactams and substitution products thereof are useful intermediates in the synthesis of biologically active lactams such as nocardicin.
