Abstract A straightforwardmethod for the synthesis of alkylidene/arylidene malonates and arylidene cyanoacetates, utilizing proline as an alternative to traditional catalysts is presented. A large number of unsaturated esters was obtained from the Knoevenagel reaction under very mild conditions and utilizing cheap reagents.
An efficient three-component organocatalytic cascade 1,3-dipolarcycloaddition reaction of in situ generated azomethine ylides with α,β-unsaturatedesters is described. This reaction afforded a small library comprised of 20 new highly substituted spirooxindole derivatives. The products were obtained in yields up to 76%, usually as single diastereomers.

The present invention is directed to substituted 2-arylmethylene-N-aryl-N′-aryl-malonamides and analogs thereof. The present invention also relates to the discovery that the compounds are activators of caspases and inducers of apoptosis. Therefore, the activators os caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.

diphenyl-substituted 3-ethoxy cyclobutanone rearranges itself by intramolecular cyclization for the in situ generation of 1-phenyl 2-naphthol, which further undergoes remote site-selective Friedel–Crafts alkylation with donor–acceptor cyclopropane to synthesize a series of γ-naphthyl butyric acid derivatives. Further control experiments for mechanistic investigations and synthetic applications have also
