WebSeveral novel bicyclo[2.2.2]lactones were synthesized from a facile one-pot reaction by the condensation of dibenzoylethylene and an arylacetonitrile in basic medium. The reaction proved to be convenient and gives high yield. The structure of the reaction products was established on the basis of their proton and carbon-13 nuclear magnetic resonance, and … An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone. The overall reaction is as follows (where the Rs can be H):
