Synthesis of Some Modified Five and Six-membered Heterocyclic Rings with Expected Biological Activity
Eman Ramadan El-Sayed Kasem;
Abstract
u,P-Unsaturated ketones (chalcones or benzalacetophenones) represent active intermediates for the preparation of several heterocyclic ring systems.
Condensation of acetophenone (54) with the appropriate aromatic aldehydes 55a-f in presence of 10% aqueous sodium hydroxide solution or piperidine afforded the corresponding a,P-unsaturated ketones 56a-f in
80-88% yields (Scheme 23).
