  • General Description 1-Indanone is a versatile cyclic ketone that serves as a key intermediate in organic synthesis, particularly in enantioselective protonation reactions and Fe-catalyzed cycloisomerizations. It can be transformed into chiral tertiary carbon centers via organocatalytic methods or converted into 3-arylidene-indan-1-one derivatives through Fe-catalyzed cycloisomerization of aryl allenyl ketones, demonstrating its utility in constructing complex molecular frameworks with high selectivity and functional group tolerance.

Straightforward organocatalytic enantioselective protonation of silyl enolates by means of cinchona alkaloids and carboxylic acids

10.1055/s-2008-1078260

The research focuses on the development of an organocatalytic enantioselective protonation method for silyl enolates using cinchona alkaloids and carboxylic acids as a chiral proton source. The experiments involved the protonation of various silyl enolates with different carboxylic acids under optimized conditions, using (DHQ)2AQN as the catalyst. The reactants included silyl enolates derived from tetralone and indanone series, along with cinchona alkaloids and carboxylic acids such as citric acid. The analyses used to determine the success of the reactions included gas chromatography (GC) for conversion monitoring, high-performance liquid chromatography (HPLC) for enantioselectivity (ee) determination, and nuclear magnetic resonance (NMR) spectroscopy for the characterization of the synthesized compounds. The study aimed to achieve high yields and enantioselectivities for the production of ketones with a tertiary stereogenic carbon center, with the goal of developing a more straightforward, atom-economic, and operationally simple method compared to existing protocols.

Fe-Catalyzed Cycloisomerization of Aryl Allenyl Ketones: Access to 3-Arylidene-indan-1-ones

10.1021/acs.orglett.8b00612

The research focuses on the cycloisomerization of aryl allenyl ketones to synthesize 3-arylidene-indan-1-ones using a cationic Fe-complex as a catalyst. This approach addresses the scarcity of methods for synthesizing this class of compounds, which are underrepresented in organic chemistry. The study explores the use of the Fe(0)-nitrosyl complex [(Ph3P)2Fe(CO)(NO)]BF4 as a π-Lewis acid catalyst, which redirects the catalytic pathway to favor cycloisomerization over the formation of furans, a common side reaction. The experiments involved optimizing reaction conditions, such as concentration and temperature, to achieve the highest yields. The optimized conditions were then used to test the scope and limitations of the reaction with various substrates, including electron-rich and -poor ortho-, meta-, and para-substituted aromatic moieties. The analyses included monitoring the reaction progress through 1H NMR-integration and isolating the products for further characterization using techniques such as IR spectra, HRMS, and crystallographic data. The study demonstrated good functional group tolerance, a broad application range, and high selectivity in the formation of the desired indanone products, marking a significant advancement in Fe catalysis and base metal catalysis.

Synthesis, characterization, crystal structure and liquid crystal studies of some symmetric naphthalene derivative molecules

10.1016/j.molstruc.2018.07.036

This research focused on the synthesis, characterization, crystal structure, and liquid crystal studies of symmetric naphthalene derivative molecules. The purpose was to investigate the mesomorphic properties of a series of symmetrical liquid crystals with a naphthalene core and long-chain flexible 4′-alkoxybenzoate moieties. The study aimed to understand the correlation between molecular structure and physical properties, particularly the effects of varying alkyl chain lengths on mesomorphic properties. The chemicals used in the synthesis included 2,6-dihydroxynaphthalene, 4-alkoxybenzoic acids, dicyclohexylcarbodiimide (DCC) as a coupling reagent, and dimethylaminopyridine (DMAP) as a catalyst. The synthesized compounds exhibited stable enantiotropic mesophases of Smectic A (SmA) and Nematic (N) phases, with the appearance of these phases being independent of the alkyl chain length. The molecular structure was determined using single crystal X-ray diffraction, revealing a dihedral angle between the naphthalene ring system and the benzoate moiety. The study concluded that the synthesized naphthalene derivatives are predominantly smectogenic and partly nematogenic, with the mesomorphic range of the smectic phase being shorter than that of the nematic phase.

Synthesis of brassinosteroids of varying acyl side chains and evaluation of their brassinolide-like activity

10.1271/bbb.68.1097

The research details a study on the synthesis and evaluation of brassinosteroids, plant hormones known for their role in cell elongation and division, which are crucial for plant growth and stress resistance. The purpose of the study was to synthesize various brassinosteroids with different acyl side chains and assess their brassinolide-like activity, using the rice lamina inclination assay with synergist indole-3-acetic acid (IAA). The researchers concluded that the introduction of a hydroxyl group in the α-position to the carbonyl group of the ester structure significantly enhanced the activity, with 2β,3β-dihydroxy-17β-[(2R,3S)-2hydroxy-3-methylpentanoyl]oxy-B-homo-7-oxa-5β-androstan-6-one showing the highest activity. The study also found that the R-form of the acyl moiety was more potent than the S-form and that modifying the terminal structure did not increase activity. Chemicals used in the synthesis process included various steroidal compounds like pregnenolone and stigmasterol, as well as a range of reagents such as dicyclohexylcarbodiimide (DCC), dimethylaminopyridine (DMAP), and protective groups like tert-butyldiphenylsilyl (TBDPS).

Selective nitrile oxide dipolar cycloaddition for the synthesis of highly functionalized β-aminocyclohexanecarboxylate stereoisomers

10.1016/j.tet.2012.09.085

This research aims to synthesize highly functionalized β-aminocyclohexanecarboxylate stereoisomers from a bicyclic β-lactam through selective nitrile oxide dipolar cycloaddition. The process involves successive regioselective iodolactonization, stereo- and regioselective nitrile oxide cycloaddition, lactone ring-opening, and isoxazoline ring-opening. Key chemicals used include N-Boc-protected amino acids, NaHCO?, KI, I? for iodolactonization, DBU for dehydroiodination, NaOEt for lactone ring-opening, and acetonitrile N-oxide generated from nitroethane, di-tert-butoxycarbonylanhydride (Boc?O), and dimethylaminopyridine (DMAP) for cycloaddition. The study concludes that the rigid ring framework in unsaturated bicyclic amino lactones significantly enhances the reactivity of the C=C double bond compared to hydroxylated cyclohexene amino esters, leading to successful regio- and stereoselective cycloaddition. The synthesized compounds, with multiple stereocenters, are promising β-amino acid analogues of bioactive compounds like Tamiflu and Zanamivir.

A titanacyclobutane precursor to alkyl-substituted titanium-carbene complexes

10.1021/om00135a016

The research focuses on the synthesis and characterization of organometallic compounds, specifically metallacycles and titanium-carbene complexes. The purpose of the study was to prepare a titanacyclobutane precursor, which was then reacted with benzophenone to yield an organic product, and further reacted with phosphines to obtain phosphine adducts of an α-substituted titanium-carbene complex. The researchers also succeeded in creating a heterobimetallic alkylidene complex by reacting the metallacycle with dimethylaluminum chloride. The conclusions drawn from the study indicate that the observed reactivity of the metallacycle is consistent with productive cleavage of the metal-containing ring, leading to the formation of titanium-carbene complexes. The chemicals used in the process include 3,3-dimethylcyclopropene, Tebbe reagent, (dimethylamino)pyridine (DMAP), benzophenone, phosphines (PMeR2, where R = Me, Ph), and dimethylaluminum chloride, among others. The study provides insights into the reactivity of metallacycles and their potential as precursors to titanium-carbene compounds.
