Novel routes for the synthesis of spiro derivatives anthrone have been designed using a Michaeladdition reaction followed by a Dieckmann condensation and Thorpe–Ziegler cyclisation. Bis-Michael addition of pyrazole-5-thione with 1,5-diarylpenta-1,4-dien-3-one gave directly a spiro derivative of pyrazole-5-thione. An enol lactone was synthesised by using mono Michaeladdition on dimedone, followed
