1′-Methyl-4′-phenyldispiro[indan-2,2′-pyrrolidine-3′,2′′-indan]-1,3,1′′-trione [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 The conformation of the title compound, C(27)H(21)NO(3), is stabilized by a weak intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring motif. The pyrrolidine ring adopts a half-chair conformation. Both of the other five-membered rings are in envelope conformations. No significant inter-molecular hydrogen bonds are observed.

Plant-Mediated Enantioselective Transformation of Indan-1-One and Indan-1-ol [PDF]
Catalysts, 2019 The main purpose of this work was to discover the way to obtain pure enantiomers of indan-1-ol. The subject of the study was the ability of the plant enzyme system to reduce the carbonyl group of indan-1-one, as well as to oxidize the hydroxyl group of racemic indan-1-ol.

Plant-Mediated Enantioselective Transformation of Indan-1-one and Indan-1-ol. Part 2 [PDF]
Molecules, 2019 The main purpose of this publication was to obtain the S-enantiomer of indan-1-ol with high enantiomeric excess and satisfactory yield. In our research, we used carrot callus cultures (Daucus carota L.), whereby the enzymatic system reduced indan-1-one and oxidized indan-1-ol.

4′-(4-Chlorophenyl)-1′-methyldispiro[indan-2,2′-pyrrolidine-3′,2′′-indan]-1,3,1′′-trione [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 In the title compound, C(27)H(20)ClNO(3), the two cyclo-pentane rings adopt envelope conformations. The pyrrolidine ring also adopts an envelope conformation (with the spiro C atom as the flap) and its least-squares plane (fitted to five atoms) makes dihedral angles of 66.50 (9), 77.36 (8) and 73.76 (8)° with the chloro-benzene ring and the two 2,3 ...

Kinetic Resolutions of Indan Derivatives Using Bacteria [PDF]
Bioscience, Biotechnology, and Biochemistry, 2002 Racemic indan derivatives have been resolved by the hydrolysis of amide bonds using Corynebacterium ammoniagenes IFO12612 to produce (S)-amine and (R)-amides. In the kinetic resolution of 1 (N-12-(6-methoxy-indan-1-yl)ethyl]acetamide), it was possible to run the reaction to 44% conversion on a 10-g scale, obtaining (S)-amine 4 ((S)-2-(6-methoxy-indan-1-

Nouveaux corps odorants dans Ie domaine des muscs polycycliques
CHIMIA, 1992 Polyalkyl-tetralins and -indans are well known as starting materials for polycyclic musks obtained by Friedel-Crafts acylation. If, instead, such hydrocarbons are subjected to benzylic (electrochemical) oxidation, new musks are obtained.

2-[(Indan-1-ylidene)amino]ethanol [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 The five-membed ring of the title compound, C(11)H(13)NO, that is fused with the aromatic ring is approximately planar (r.m.s. deviation = 0.037 Å) despite the presence of the sp(3)-hybrid-ized ethyl-ene linkage. The hy-droxy group of the N-bound hy-droxy-ethyl chain serves as hydrogen-bond donor to the azomethine N atom of an adjacent mol-ecule ...
