- Synthesis, antimicrobial, and anti-inflammatory activities of acetamido pyrrolyl azoles
-
The acetamido pyrrolyl oxazoles/thiazoles/imidazoles were prepared and tested for their antimicrobial and anti-inflammatory activities. The nitro substituted acetamido pyrrolyl thiazole (11f) and pyrrolyl imidazole (12f) exhibited promising antibacterial activity against K. pneumoniae. The compound 12f showed good antifungal activity against P. chrysogenum. The methoxy acetamido pyrrolyl oxazole (10c) displayed potential anti-inflammatory activity.

- Synthesis and process optimization of amtolmetin: An antiinflammatory agent
-
Efforts toward the synthesis and process optimization of amtolmetin guacil 1 are described. High-yielding electrophilic substitution followed by Wolf-Kishner reduction are the key features in the novel synthesis of tolmetin 2 which is an advanced intermediate of 1.

- Friedel - Crafts acylation of pyrroles and indoles using 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) as a nucleophilic catalyst
-
1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) has been shown to be an effective catalyst for the regioselective Friedel - Crafts C-acylation of pyrroles and indoles in high yields. A detailed mechanistic study implies that DBN is acting as a nucleophilic organocatalyst, with the X-ray crystal structure of a key N-acyl-amidine intermediate having been determined for the first time.
