A cascade inter-intramolecular double Michael strategy for the synthesis of highly functionalized cyclohexanones from curcumins and arylidenemalonates is reported. This works in presence aqueous KOH using TBAB as a suitable phase transfer catalyst at room temperature. The are formed major products moderate to excellent yields with complete diastereoselectivity most cases. triple adduct, tetrahydrochromen-4-one, also side product few cases diastereoselectivity.

Abstract In this research, investigation of one‐pot multicomponent reactions (1E,6E)‐1,7‐bis(4‐hydroxy‐3‐methoxyphenyl)hepta‐1,6‐diene‐3,5‐dione (curcumin), primary amines, and activated acetylenic compounds in an aqueous medium at room temperature the presence catalytic amounts silica‐coated magnetic nanoparticles functionalized by iminodiacetic acid‐copper (Fe 3 O 4 @SiO 2 /IDA‐Cu) was studied which produced 1,4‐dihydropyridine‐2,3‐dicarboxylate high yields. The advantages procedure were easy separation products catalyst, yields products, reusability synthesized good rate reactions.
