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 ...

4′-(4-Bromophenyl)-1′-methyldispiro[indan-2,2′-pyrrolidine-3′,2′′-indan]-1,3,1′′-trione [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 En el compuesto del título, C27H20BrNO3, el anillo de pirrolidina adopta una conformación de media silla, mientras que los otros anillos de cinco miembros adoptan conformaciones de envoltura aplanadas con los átomos de espiro C como los átomos de flap. Se produce un enlace de hidrógeno C-H-O intramolecular, que genera un anillo S(6).

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.

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.

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 ...

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.
