A chemoselective cascade cycloaddition reaction is developed for green and efficient access to cyclopenta[c]pyridine derivatives. Simple and inexpensive NaOH is used as the sole catalyst for this process. The δ-carbon of cyclopropyl ester is activated as a nucleophilic carbon to initiate highly chemoselective cascade reactions. Cyclopenta[c]pyridines bearing various substituents are afforded in excellent

Triazoles are famous as an antifungal agent. Itraconazole and fluconazole are the best examples of antifungal drugs available in the market, which consist of an active triazole moiety. Pyrimidines are also bioactive molecules which shows multiple bioactivity. It’s an effort to synthesize pyrimidine clubbed triazole to enhance bioactivity. To synthesize new active pyrimidine clubbed triazole biomolecule

Chemo-/Regio-Selective Ultrasound-Assisted Synthesis of New Spirooxindole-Pyrrolidines/Spirooxindole-Pyrrolizines: Synthesis, Antimicrobial and Antitubercular Activities, SAR and in silico Studies
strain of [BS]. Compounds (MIC = 3.125 µg/Ml) and (MIC = 1.56 µg/mL) demonstrated strong antitubercularactivity in the antitubercularactivity assay when compared to the conventional medications Rifampicin (MIC = 0.2 µg/mL) and INH (MIC = 0.1 µg/mL). We also report, for the first time, in vitro antimicrobial activity of some previously reported spiro compounds and 12 g.
