Friendly and Efficient Synthesis of Chalcone Derivatives under Solvent-Free Condition
Abstract: A series of various chalcone derivatives were synthesized using solvent free technique by grinding different substituted benzaldehyde, acetophenone and NaOH pellets at room temperature, and same reactions were carried out under solvent condition (50% EtOH). The reaction time needed to synthesize desired chalcones was 15–45 min; and 13 h stirring in the presence of solvent. All compounds were identified by comparison of their melting points with that of the substrates; …

Synthesis and Antimicrobial Activity of New Heterocyclic Compound Containing 5-Bromobenzofuran
Abstract: Several pyridine derivatives were synthesized via reaction of 2-acetyl 5-bromobenzofuran and 1,3-diphenyl-1 H-pyrazole-4-carbaldehyde 2 gave chalcone 3 which was exploited as a starting material. Structures of newly synthesized derivatives were confirmed by elemental analysis, spectral data, chemical transformation and alternative synthetic route whenever possible. Also, the newly synthesized derivatives were screened towards some microorganism.
