Facial Regioselective Synthesis of Novel Bioactive Spiropyrrolidine/Pyrrolizine-Oxindole Derivatives via a Three Components Reaction as Potential Antimicrobial Agents
This article presents the synthesis of new derivatives of spirooxindole-spiropiperidinone- pyrrolidines 6a–j and spirooxindole-spiropiperidinone-pyrrolizines 8a–j, through a 1,3-dipolar cycloaddition reaction of azomethineylides generated from isatin, sarcosine, and l-proline, through a decarboxylat...

| Summary: | This article presents the synthesis of new derivatives of spirooxindole-spiropiperidinone- pyrrolidines 6a–j and spirooxindole-spiropiperidinone-pyrrolizines 8a–j, through a 1,3-dipolar cycloaddition reaction of azomethineylides generated from isatin, sarcosine, and l-proline, through a decarboxylative route with dipolarophile 4a–j. All of the newly synthesized compounds were evaluated for their antimicrobial activities and their minimum inhibitory concentration (MIC) against most of the test organisms. The tested compounds displayed excellent activity against all of the tested microorganisms. |
