Efficient classical synthesis of aminoazines under microwave irradiation

In the present study, Aminoazines were prepared from the reaction of amidrazone hydroiodide with various aromatic aldehydes in the presence of a solid base under microwave irradiation with power level of 850 W for 2-7 min in high yields. The amidrazone hydroiodide can also be prepared by the reaction of S-methyl isothiobenzamide hydroiodide and hydrazine in methanol under nitrogen gas. All synt...

An efficient synthesis of pyridoxal oxime derivatives under microwave irradiation.

Quaternary salts of pyridoxal oxime have been synthesized by the quaternization of pyridoxal oxime with substituted phenacyl bromides using microwave heating. Microwave-assisted rapid synthesis was done both in solvent (acetone) and under solvent-free conditions. Good to excellent yields (58%-94%) were obtained in acetone in very short reaction times (3-5 min) as well as in the solvent-free pro...

Solvent-free synthesis of functionalized flavones under microwave irradiation.

[reaction: see text] Eco-friendly direct solvent-free synthesis of flavones is achieved by microwave irradiation of phloroglucinol and beta-ketoesters. Heating with microwaves versus under classical conditions was shown to be higher yielding, cleaner, and faster. The reaction goes through a cycloaddition of an alpha-oxo ketene intermediate followed by an uncatalyzed thermal Fries rearrangement.
