Circular dichroism of diastereomeric 3,3′-di-t-butyl-1,1′-spirobi-indans

, 1978
Two diastereomeric 3,3′-di-t-butyl-1,1′-spirobi-indans, (1R,3S,3′S)-(1a) and (1S,3S,3′S)-(1b), have been prepared; their c.d. spectra are similar to each other in spite of the opposite configuration at the spiro centre.

2-(2-Thiazolylhydrazono)indan-1,3-dione

Acta Crystallographica Section C Crystal Structure Communications, 1997
The structural results clearly indicate that 2-(2-thiazolylhydrazono)indan-1,3-dione, C12H7N3O2S, exists as a keto-hydrazone tautomer in the solid state. The indandione and thiazolylhydrazone groups are connected by a C=N bond and the H atom bonded to N1 refines with a normal temperature factor. The entire molecule is essentially planar.

Conformational analysis of indan-1-ols

Journal of the Chemical Society B: Physical Organic, 1971
The conformations of some new indan-1-ols have been assigned from their mode of synthesis and from their n.m.r. spectra. Those with a substituent RCH2 on C-1 show an unexpected correlation between the chemical shifts of the methylene protons and the configuration of the 2,3-substituents.

Electron Transport in 1,3-Bis(dicyanomethylene)indans

, 1996
Upon investigation of the photoconductive properties of polycarbonate doped with 1,3-bis(dicyanomethylene)indans, a large, temperature independent quantum yield for charge generation was observed.

Phenyl indane from acorus calamus

Phytochemistry, 1986
Abstract Besides three known compounds, two new compounds, namely Z-3-(2,4,5-trimethoxy phenyl)-2-propenal and a new phenyl indane have been isolated from the rhizomes of Acorus calamus. These compounds have been characterized from their spectral data and by synthesis.

Synthesis of spiro-indanes by cycloaddition strategy

Journal of the Chemical Society, Perkin Transactions 1, 2001
Various 2,2′-spirobiindane-1,3-dione derivatives which are useful precursors for the synthesis of unsymmetrical benzoannelated fenestranes are reported via [2+2+2] and [4+2] cycloaddition reactions as key steps.

Reductive deoxygenation of indan-1-ols by

Tetrahedron Letters, 1995
Abstract Sodium cyanoborohydride in the presence of zinc iodide is found to reduce epimeric tertiary alcohols, whose carbinol group is a stereogenic center in a a stereoconvergent ...

Facile transformation of benzyl ethers, alcohols, amides and amines to substituted indans

, 1998
The elimination of HX from ArMe2CX (X = OH, OMe, NHCOMe, NH2) in sulfuric acid-liquid hydrocarbon leads easily to indan formation.
