OBJECTIVE The initial objective of this study was to synthesize and evaluate 2-substituted 4-arylidene- 5(4H)-oxazolones for their potential anticancer properties. METHODS A simple, mild and non-hazardous synthetic methodology has been developed for the preparation of 2-substituted 4-arylidene-5(4H)-oxazolones. The methodology involved lemon juice mediated condensation of N-acyl glycine derivatives including
cycloaddition reaction was developed for the expedient synthesis of pharmacologically interesting 3-aryl substituted isoxazolines and isoxazoles through C[double bond, length as m-dash]C bond cleavage. Copper nitrate is employed as a reaction promoter and precursor of nitrile oxides. The given approach features a new mode of cycloaddition from olefinic azlactones, copper nitrate and unsaturated compounds
