A FeCl3·6H2O-mediated reaction of [60]fullerene with amidoximes for the preparation of fulleroimidazolines has been presented. This reaction shows a wide substrate scope, and the products obtained from alkyl-substituted amidoximes are first disclosed. In addition, a possible mechanism is proposed.

A series of fluorinated propargylamines have been synthesized from the one-pot three-component reaction of fluorobenzaldehyde, aniline and phenylacetylene under solvent-free and microwave irradiation. The fluorinated propargylamines were then further transformed to chalcones or quinoline derivatives respectively depending on the different structures of propargylamines.Graphical abstractA series of fluorinated propargylamines have been synthesized from the one-pot three-component reaction of fluorobenzaldehyde, aniline and phenylacetylene under solvent-free and microwave irradiation.

•One-pot catalyst-free synthesis of γ-hydroxybutenolides.•The method uses water as solvent which is environmentally friendly.•The product structure was confirmed by single crystal X-ray diffraction analysis.•The synthetic route is straightforward and convenient for gram-scale synthesis.A one-pot gram-scale synthetic route for the preparation of γ-hydroxybutenolides via catalyst-free annulation of α-amino acids with α-keto acids in water is reported. The method shows many advantages such as readily available starting materials, mild reaction conditions, operational simplicity, acceptable yields, and requiring no extra catalysts or additions. Furthermore, the method is innocuous to the environment, also is valuable to industry.
