is a nitrogen-containing heterocyclic ring. Also provided are method for treating or preventing cancer in a subject by administering a therapeutically effective amount of a heteroaryl-containing isoflavone, or a pharmaceutically acceptable salt or prodrug thereof, to a subject in need of treatment. Also provided is a method for the synthesis of 2-substituted isoflavones by first reacting deoxybenzoins with a phase transfer catalyst to provide a 2-(alkylthio)isoflavone; second deprotecting the 2-(alkylthio)isoflavone; and third applying selective debenzylation to form the final compound.
