Tethering of two biologically active molecules in a single unit is considered as a captivating solution for the extension of existing antibiotics. β-Lactams which display a vast array of biological properties due to various ring substitutions continue to attract the attention of synthetic chemists. The incorporation of the 'isoxazole' nucleus in its appendage is known to enhance the properties of β-lactam compounds. Its inclusion in the compounds offers decreased toxicity, increased efficacy, and improved pharmacokinetics spectrum. In the reported work, we highlight the efficient use of 1,3-dipolar cycloaddition reaction to synthesize novel isoxazole/dihydroisoxazole ring-linked β-lactam hybrids using 3-propargyloxy-β-lactams/3-allyl-β-lactams as synthons. The methodology devised has been found to be highly regioselective and generalized for the selected substrates to provide a variety of novel hybrid compounds under elementary reaction conditions. The synthesized compounds have been well characterized by various spectroscopic techniques and optimized reaction conditions for both types of hybrid compounds have been studied.
