An intramolecular anti-hydroarylation of propargylarenes proceeds smoothly with a palladium/carboxylic acid catalyst to form indenes straightforwardly. Indenes having various functional groups were easily prepared. The novel synthetic method is applicable to double hydroarylation to form a 1,5-dihydro-s-indacene.

An efficient synthesis of chiral 3-arylindanones via iridium-catalyzed asymmetric hydrogenation of 3-arylindenones has been developed. The reaction showed good compatibility with various functional groups, delivering a variety of 3-arylindanones in excellent yields and with good enantioselectivities. The reaction was also carried out on a gram-scale, delivering the product in quantitative yield. In addition, the products can be easily derivatized and transformed into natural products and pharmaceutical agents.

An efficient protocol for the straightforward, single-step synthesis of 3-aryl-1-indanones from 2′-iodochalcone via reductive Heck reaction using phosphine free, stable and reusable binaphthyl stabilized palladium nanoparticle (Pd-BNP) as a catalyst has been described. An immense array of substrate scope with electron-rich and deficient 2′-iodochalcones have been synthesized. Further derivatization of product indanones have been achieved successfully. The heterogeneous nature of the Pd-BNP has been validated by centrifugation test and mercury poisoning experiment. Pd-BNP has been successfully recycled up to 5 cycles without any significant loss in reaction yield and particle size of nanoparticles, confirmed by TEM analysis. (Figure presented.).

Friedel-Crafts-type acylation of alkenes with acyl chlorides has been successfully conducted with a wide substrate scope by the combined use of AlCl3 and 2,6-dibromopyridine. Trisubstituted alkenes afford allylketones or vinylketones depending on the presence or absence of hydrogen atom(s) at the β-position to the acylation site, while monosubstituted alkenes exclusively afford vinylketones.
Stereoselective Photodimerization of 3-Arylindenones in Solution and in the Solid State
Uemura, Naohiro,Ishikawa, Hiroki,Tamura, Naoki,Yoshida, Yasushi,Mino, Takashi,Kasashima, Yoshio,Sakamoto, Masami
, p. 2256 - 2262 (2018/02/23)
Photodimerization of 3-arylindenones in solution and in the solid state was examined. Irradiation of 3-arylindenones in benzene exclusively gave C2-symmetric anti-HH cyclobutane dimers in good yields. In contrast, photolysis in the solid state

A palladium-catalyzed enantioselective reductive Heck reaction of enones using monodentate phosphoramidite ligands is described. α,α,α’,α’-tetraaryl-1,3-dioxolane-4,5-dimethanol (TADDOL)-based phosphoramidites with palladium(II) acetate, and N-methyl dicy
Regioselective quadruple domino aldolization/aldol condensation/Michael/ SNAr-cyclization: Construction of hexacyclic indeno-fused C-nor-D-homo-steroid frameworks
Chanda, Tanmoy,Chowdhury, Sushobhan,Ramulu, B. Janaki,Koley, Suvajit,Jones, Raymond C.F.,Singh, Maya Shankar
, p. 2190 - 2194 (2014/03/21)
An operationally simple and highly atom-economic anionic quadruple domino reaction sequence for the synthesis of hexacyclic indeno-fused naphthalene/quinoline molecules having structural resemblance with the C-nor-D-homo-steroid nucleus has been developed. Promoter and solvent specificity, regioselectivity and mechanistic details were experimentally established. Catalyst concentration and solvent dependent switching of domino steps creating four new C-C bonds are discussed.
Molecular iodine mediated cyclization reactions of 2-(1-alkynyl)benzylic alcohols to substituted indenones

An efficient I2-mediated approach to the synthesis of disubstituted indenones from readily available 2-alkynylbenzyl alcohols in the presence of H2O has been developed. These results are different from the known iodocyclization react
