In this study, ten 3-substituted indole derivatives at the 3rd position of indole nucleus were synthesized via Mannich reaction with microwave assisted synthesis and the conventional reflux heating method. Microwave assisted synthesis is more preferrable than reflux method since the microwave irradiation lead to a higher product yields with better purity and improved energy efficiency with shortened reaction time. The structures of 3-substituted indole derivatives were characterized by FT-IR, elemental analysis, 1H NMR and 13C NMR spectroscopy

: Triazoles are five-membered aromatic heterocyclics, which could exist in two isosteric forms (1,2,3-triazoles and 1,2,4-triazoles) presenting huge applications in medicinal, agricultural, supramolecular and materials sciences. The drugs fluconazole, ribavirin, cefatrizine and tazobactam, and the herbicides cafenstrole and metosulam are famous examples of triazoles. The aim of this review is to present the main recent examples of Microwave-Assisted Organic Synthesis (MAOS) applied for the synthesis end functionalization of 1,4- and 1,5-disubstituted-1,2,3-triazoles, 1,2,4-triazoles, 3-amino-1,2,4-triazoles, 1,2,4-triazol-3-one and 1,2,4-triazol-3-thiol derivatives. Worth of noting, despite some previous reviews about triazole synthesis, none of them focused exclusively on the importance of MAOS technic in the obtention and derivatization of these compounds.

Abstract The energy efficiency of the microwave-assisted synthesis of pyrrolidinones was demonstrated using catalytic loading of 1,1’-butylene-bis(3-sulfo-3H-imidazol-1-ium) chloride as a sulfonic acid functionalized ionic liquid in ethylene glycol as green solvent. The effect of electron donating and electron withdrawing groups on aniline derivatives was studied under conventional heating and microwave irradiation. Furthermore, the cation effect of ionic liquids containing sulfonic groups on the catalytic efficiency for the synthesis of ethyl-1-phenyl-2-(4-chlorophenyl)-4-hydroxy-5-oxo-2,5-dihydro-1H-pyr-role-3-carboxylate was investigated under conventional heat. The experimental results exhibited that there is a relationship between catalytic efficiency and the number of sulfonic groups and imidazolium moieties linked by carbon spacer.
