Sarkar and Mukhopadhyay have developed a three-component green methodology to synthesize ethyl/methyl 4-hydroxy-5-oxo-l,2-diaryl-2,5-dihydro-lH-pyrrole-3-carboxylates under admicellar catalysis by Ti02 nanoparticles at room temperature [59]. The catalyst in aqueous CTAB solution promotes the formation of admicelles, and the reaction occurs in admicellar environment. A number of aromatic aldehydes 51, amines 9, and diethyl/dimethyl acetylene dicarboxylate (DEAD/DMAD, 70) react to give the products 71 in good yields (Scheme 23). In this reaction, aldehydes have also been replaced with isatin 55 to give spiro-fused products. [Pg.171]
