The synthesis of two series of derivatives containing the quinazolinone‐4 moiety is described. 3‐Amino‐2(1H)‐thioxo‐4(3H)‐quinazolinone (1) was subjected to reactions with halogenoketones and halogenoaldehydes, leading to the production of the corresponding ketones, aldehydes, Schiff bases, and 6‐oxo‐1,4,5‐thiadiazin[2,3‐b]quinazoline derivatives. Subsequently, 1 was condensed with selected α,β‐unsaturated
