Abstract:
The divergent and selective syntheses of two types of annelated β-lactams, namely, furan- and tetrahydropyridine-fused 2-azetidinones, have been accomplished directly from 2-azetidinone-tethered oxazolidine-enynes through gold catalysis.

Introduction: A series of (R)-(-)-4-Phenyl-2 oxazolidinone based azetidinones (4a-i) were synthesized from the reaction of (2-Oxo-4-phenyl-oxazolidin-3-yl) acetic acid with aromatic imines (3a-i) in the presence of Thionyl chloride and Triethylamine as a base. Methods: The transformation proceeds through the formation of acid chloride to ketene which finally forms the azetidinones through [2+2] cycloaddition with aromatic imines. Products obtained were screened to evaluate their antibacterial activity with respect to known bacteria like Escherichia Coli (E. Coli) and Bacillus subtilis. Results

A synthesis of a novel series of cis-2-azetidinones 2a–c was carried out by the cycloaddition reaction of imine 1a–c and chloroacetyl chloride in dry dichloromethane at 0–5 °C using triethylamine. The cycloaddition of the Schiff bases with chloroacetyl chloride resulted in the corresponding major product cis-2-azetidinone stereoisomers 2a–c. The synthesized compounds were characterized by analytical and spectral techniques (infrared, 1H NMR, 13C NMR, and elemental analysis).

Abstract:
Azetidinones were synthesized from p-anisidine in two steps. First the Schiff's bases were prepared by reacting the hydrazide of an anisidine derivative with different aromatic aldehydes. Cyclocondensation of the Schiff's bases with chloroacetyl chloride in the presence of triethylamine resulted in the formation of the corresponding azetidinone analogues. The structures of the newly synthesized compounds were confirmed by IR, 1H NMR and mass spectroscopic analysis. The antibacterial and antifungal potential of the synthesized compounds were evaluated by the agar disc method.

Globally, many diseases with unmet therapeutic needs persist, including cancer, tuberculosis, and various infectious diseases. The rapid development of new drugs is crucial to counteract these health challenges.

The synthesis of strained tricyclic azetidinones was achieved by free radical cyclization of N-substituted azetidinones involving a tributyltin hydride/AIBN mediated chain reaction. The 5-exo cyclization led to benzo carbapenems 10, 12, and 13, which were relatively unstable in solution. The 6-exo mode, however, afforded stable benzo carbacephems 20, 22, 24, and 25.

Drug discovery and chemical synthesis have been globalizing the pharmaceutical market. The process of drug discovery takes along many stages of drug development viz., targeting a disease, repurposing an existing drug, conjugating obsolete drugs with natural compounds, searching for different receptors for specificity and rationality, and finally testing the toxicity before exposing it tothe clinical trial. This long path from targeting to clinical trial takes many efforts of scientists and chemists. When entering into the drug development core, the heterocyclic compounds were ruling the world
