[ 1 ] - New Strategy for the Synthesis of Morpholine Cores: Synthesis from N-Propargylamines
Functionalized morpholines have attracted much attention due to their potential biological activities. Despite the wide importance of morpholine derivatives in drug design of various pharmacological agents, the development of new approaches to their synthesis remains relatively unexplored. Given the low cost and easy availability of N-propargylamines, the synthesis of functionalized morphol...
[ 2 ] - DFT calculations on quetiapine hemifumarate as a pharmaceutical compound for the treatment of schizophrenia
In this work, the optimization calculations were carried out on quetiapine hemifumarat, 4, and its analogues, 1-5. These calculations were carried out using the B3LYP/6-31G(d) level of theory. The DFT calculations clarified a boat structure for dibenzothiazepine moiety of the molecule which piperazine moiety has a chair conformation. Thermal energies (E), enthalpies (H), and free energies (G) o...
[ 3 ] - Experimental and Theoretical Studies on a Derivative of Tetrahydro-1H-Benzodiazepine
N-Cyclohexyl-2,4,4-trimethyl-2,3,4,5-tetrahydro-1H-benzo[b][1,5]diazepine-2-carboxamide (5) was synthesized using an efficient, highly recyclable and eco-friendly catalyst heteropolyacid/triethoxysilyl)propyl]isonicotinamide (HPA/TPI-Fe3O4 nanoparticles) in one-pot. The compound 5 was characterized by FT-IR,1H NMR, 13C NMR, mass spectra, and elemental analysis. The theoretical calculations on 5...
[ 4 ] - γ-Fe2O3@HAP-Fe2+ NPs: An Efficient and Eco-Friendly Catalyst for the Synthesis of Xanthene Derivatives in Water
Efficient and environmentally friendly syntheses of xanthenes derivatives by using γ-Fe2O3@HAP-Fe2+ NPs as a catalyst has been carried out. The catalyst can be readily isolated by using an external magnet and no obvious loss of activity was observed when the catalyst was reused in eight consecutive runs. The procedure has several advantages, such as economic...
