A cascade aza‐Michael/Aldol annulation of 2‐arylideneindane‐1,3‐diones with in situ generated Huisgen zwitterions has been developed. This reaction afforded the desired products in moderate to good yields (up to 87%) with excellent chemo‐ and diastereoselectivity (up to 20:1). This strategy allows facile diastereoselective preparation of biologically important indenopyrazoline derivatives containing

An organocatalytic enantioselective Tamuracycloaddition between homophthalic anhydrides and 2-arylidene-1,3-indanediones has been developed. With 2 mol% of commercially available (DHQD)2PYR, a wide range of enantioenriched spiro-1,3-indanedione derivatives were obtained in good-to-excellent yields (68–98%), excellent diastereoselectivities (99 : 1 dr) and moderate-to-excellent enantioselectivities
