Brocato, Emanuela published the artcileA new palladium-catalyzed synthesis of 3-substituted 2-arylidene-2,3-dihydro-1H-inden-1-ones, Category: tetrahydropyran, the publication is Tetrahedron Letters (1992), 33(48), 7433-6, database is CAplus.
Sequential oxidative additions of 2-IC6H4CH2X (X = CO2Me, CO2CHMe2, CONEt2), carbon monoxide insertion, reductive coupling with HCCY (Y = Ph, 4-MeOC6H4), nucleophilic attack by the activated methylene group, and protonation with metal elimination afford the title compounds I in a one-pot catalytic process.
