Abstract A protocol for the stereoselective synthesis of alkylidenephthalides and indanediones has been developed through reaction o ‐hydroxychalcones their styrenyl analogues, respectively, with 3‐sulfonylphthalide. The mechanism former involves Michael addition‐E 2 elimination sequence, while latter a [4+1] Hauser‐Kraus annulation. mechanistic studies reveal that strategically positioned phenolic group plays pivotal role in observed reactivities. alkylidenephthalides, which are latent 1,4‐dicarbonyl compounds, were further converted to triarylfurans under Paal‐Knorr conditions good excellent yields. This unravels several key features such as substrate specific product formation, namely, from chalcones, vinylogous chalcones 3‐sulfonylphthalide well surrogates furan synthesis.

Abstract A simple and convenient protocol has been demonstrated for the construction of spiro[chroman‐3,2′‐indanedione] via Oxa‐Michael/Michael cascade reaction sequence using 2‐arylidene‐1,3‐indanedione ( E )‐2‐(2‐nitrovinyl)phenol. This [4+2] cyclisation results in generation two stereocentres along with an all carbon quaternary centre good to high chemical yields upto 93 %. triple approach was carried out [1+1+4] protocol.
