beta -Keto-substituted beta -nitrostyrenes were synthesized by condensation
of benzaldehyde and its analogs with nitroacetone or nitroacetophenone. Re
actions of gem-acetyl(benzoyl)nitrostyrenes with a series of CH acids were
studied, and the products of nucleophilic addition reactions with malonic,
cyanoacetic, and acetaminomalonic esters were obtained. With acetylacetone,
along with linear addition products, a heterocyclization product was isola
ted, substituted dihydrofuran.
