Solventless lactam synthesis by intramolecular cyclizations of alpha-iminoester derivatives under microwave irradiation.
We have previously reported a new synthesis of amides from esters and amines under microwave irradiation, offering much higher yields than those achieved with conventional heating [1]. We have now extended these studies to the ring closure of neat iminoesters I2, I3 and I4-I6 to give five- and six-membered ring lactams L5, L6 and larger lactams L7-L9 (where I means imine and L means lactam), re...
متن کاملAn 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...
متن کاملFacile Synthesis of Hydantoin Derivatives under Microwave Irradiation
In recent years, microwave irradiation using commercial domestic ovens for the optimization and acceleration of organic reactions has rapidly increased1−2.It has been reported that a variety of reactions such as Dielsalder , ene, Claisen reactions , Fischer cyclization, synthesis of heterocycles , hydrolysis of esters , hydrogenation, deprotection of benzyl ester, deacetylation of diacetates, o...
متن کاملOne-pot synthesis of Benzimidazole derivatives under microwave Irradiation and solvent-free condition
A simple, fast, efficient and environmentally friendly method for synthesis of benzimidazole and its 2-alkyl, aryl and heteroaryl substituted derivatives was developed using zeolite HY. Two component cyclolcondensation of 1,2-phenylenediamine (o-phenylenediamine) and commercially available carboxylic acids catalyzed by zeolite HY without any solvent, under microwave irradiation led to formation...
متن کاملEfficient 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...
