Fe3O4 Nanoparticles as an Efficient and Magnetically Recoverable Catalyst for the Synthesis of α,β-Unsaturated Heterocyclic and Cyclic Ketones under Solvent-Free Conditions

Autor: Hossein A. Oskooei, Tooba Alishiri, Majid M. Heravi

Publikováno v: Synthetic Communications. 43:3357-3362

An efficient and green procedure has been developed for the synthesis of monoarylidenes of cyclic and heterocyclic ketones. The reaction was carried out under solvent-free conditions in the presence of a catalytic amount of nanosized magnetite (Fe3O4

Ultrasound-Mediated Willgerodt–Kindler Reactions: Non-thermal Synthesis of Thioacetamides

Autor: M. Saeed Abaee, Tooba Alishiri, Mohammad M. Mojtahedi

Publikováno v: Phosphorus, Sulfur, and Silicon and the Related Elements. 186:1910-1915

Non-thermal, solvent-free condensation of several aryl methyl ketones with amines and elemental sulfur is efficiently conducted using ultrasonic irradiation within short time periods. Consequently, various thioacetamides are conveniently synthesized.

Superparamagnetic iron oxide as an efficient catalyst for the one-pot, solvent-free synthesis of α-aminonitriles

Autor: Tooba Alishiri, M. Saeed Abaee, Mohammad M. Mojtahedi

Publikováno v: Tetrahedron Letters. 50:2322-2325

Superparamagnetic Fe 3 O 4 is shown to act as a very efficient catalyst for the one-pot, three-component synthesis of α-aminonitriles from aldehydes, amines, and TMSCN. The catalyst is easily recovered by the use of an external magnet and reused in

Dimethyl Acetylenedicarboxylate as a Building Block in Heterocyclic Synthesis†

Autor: Tooba Alishiri, Majid M. Heravi

Dimethyl acetylenedicarboxylate (DMAD) is an electron-deficient acetylenic compound having two reactive ester groups. It is a privileged and advantaged molecule, which participates easily and practically in heterocyclization. Due to the presence of t
