Synthesis and Heteroannulation of Pyridine and Related Heterocyclic Systems Having Surface and Biological Activities

Fluorene Derivatives with Multi‐addressable Properties: Synthesis, Characterization, and Reactivity

“…The structures of 9a, b and 12a, b were confirmed from both analytical and spectroscopic data. Finally, pyridine derivative 13 was produced by Scheme 5 Synthesis of surface active agents (20)(21)(22)(23)(24) refluxing 4c with cyanoacetamide in acetone using potassium hydroxide as a basic catalyst (Scheme 3). The structures of the synthesized compounds were assigned on the basis of elemental analysis and spectral data (cf.…”

“…We have been involved in the development of simple procedures for the synthesis of effective, cheap, functionally substituted heterocycles with biological activities [13][14][15][16][17][18][19]. The derivatives of fatty compounds based on these heterocyclic compounds can be used as valuable oleochemicals [20][21][22]. We therefore aimed to combine pyridine, pyrimidine, and pyrazole derivatives with a fluorene moiety.…”

Synthesis of Potential Pharmaceutical Heterocycles as Surface Active Agents

“…These surface active agents are inexpensive to produce and have various applications in industry, because of applications as emulsifiers, foam stabilization, wetting agents, facilitate solubilization and several biotechnological processes [40][41][42][43][44][45][46]. Addition of number of moles of propylene oxide (10 moles) to the synthesized compounds (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) which have active hydrogen atoms in the presence of KOH as a catalyst produced nonionic surface active agents (21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37), respectively, which may have broader formulation flexibility. The structure of propoxylated products (21)(22)(23)(24)(25)…”

“…Oleochemicals are necessary to a variety of applications such as plastics, surface treatments, paints, lubricants, pharmaceuticals, pesticides, detergents, soaps, textiles, and cosmetic [14][15][16][17][18][19][20]. Extending our past research in this area [21][22][23][24][25][26], we sought to prepare some new isoxazole, pyrazole, puran, pyridine and pyrimidine derivatives and evaluating their surface and biological activities to determine suitability for the applications above.…”

Synthesis, Surface, and Antimicrobial Activity of Hydrophobically Thiadiazole, Pyridazine, and Pyrimidine Systems Based on Surface Active Agents

“…Surface active agents are compounds containing hydrophobic and hydrophilic groups, which lead to an increase in solubility, moisturizing, foam, and other surface properties, making them possess many applications from consumer to industrial materials such as toiletries, emulsifiers, cleaning detergents, cosmetic agents, and antistatic . Many surface active agents containing heterocyclic anomalies are extensive biological activity, which can be introduced in important industries . These facts encouraged us to synthesize thiadiazole 2 from palmitic acid as a useful starting point for the synthesis of heterocyclic rings for use in laboratory applications to facilitate the development of more effective antimicrobial agents.…”
