ones has been described through a Michael/alkylation cascade reaction of 4-arylidenepyrazol-5-ones with diethyl 2-bromomalonate catalyzed by (DHQ)2AQN. The reaction afforded selectively the corresponding spirocyclic compounds with 30–83% yield, diastereoselectivities ranging from 60:40 to >95:5 and 26–93% enantiomeric excess under mild reaction conditions. Moreover, we performed two selective transformations
