A simple and straightforward method for the synthesis of primary α-ketoamides has been discovered. The reaction represents the first example of benzylimidates directly converting to primary α-ketoamides by using sustainable molecular oxygen as an oxidant. This reaction proceeds in the presence of copper(II) salt via cleavage of benzylic C–H and C–O bonds of the benzylimidates with liberation of alcohols

4-(5-fluoro-2-substituted-1H-benzimidazol-6-yl)morpholine derivatives has been synthesized and screened for their α-glucosidase inhibitory potential. All molecules showed a considerable α-glucosidase inhibitory potential with IC50 values ranging from 20.46 ± 0.21 to 0.18 ± 0.01 µg/mL when compared with the acarbose (IC50 = 8.16 ± 0.12 µg/mL) as the standard. Compound 4 k having methoxy group on phenyl ring

The synthesis of 2-substituted benzimidazoles from the reaction of o-phenylenediamine and an imino ester hydrochloride with ultrasoundirradiation is reported. The procedure has an eco-friendly and simple workup with good yield in a short time.
procedure is described for the synthesis of 2-substituted perimidines involving the reaction of 1,8-diaminonapthalene with iminoester hydrochlorides of substituted phenylacetic acids under microwave irradiation. This leads to good yields in short reaction times. The results were compared with those that used conventional heating. This new method may be preferable for the synthesis of perimidines.
