Abstract The interaction of the arylmethylidene derivatives of 3H-furan-2-ones with 3-amino-1,2,4-triazole was studied. The structure of the final products depends on reaction conditions and reagent ratio.
An asymmetric [3+2] cycloaddition reaction ofN-2,2,2-trifluoroethylisatin ketimines and 3-alkenyl-5-arylfuran-2(3H)-ones was developed with 1 mol% thiourea–tertiary amine.

The utilization of green chemistry techniques is dramatically reducing chemical waste and reaction times and has recently been proven in several organic syntheses and chemical transformations. To illustrate these advantages sulphamic acid is used as a novel recyclable heterogeneous catalyst in the cyclization of Perkin condensation product a-arylidine-b-benzoyl propionic acid to achieve biologically potent 1-phenylnaphthalene system and pericarbonyl lactone lignans under two experimental conditions i.e., conventional and microwave irradiation. The generality of this protocol has been demonstrated by synthesizing a variety of substituted 1-phenyl-naphthalene systems in excellent yields, short reaction time and with good purity.
