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.

N-Insertion of Diazonium Salts Into Ketone Derivatives. [PDF]
Angew Chem Int Ed EnglDiazonium salts insert into ketones and their silyl enol ethers through a sequence of α‐azenylation and ring expansion via an N‐iminoaziridinium species. Coupled with an efficient N‐N bond cleavage, this protocol offers a mild alternative to Beckmann rearrangements and a powerful tool for skeletal editing of ketones.

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 ...

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.
