Phenyl indane from acorus calamus
Phytochemistry, 1986Abstract 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 2-Sulfonyl Indenes and Indanes
The Journal of Organic Chemistry, 2019In this paper, we developed facile and high-yield synthetic routes for the preparation of 2-sulfonyl indenes and indanes, including: (i) Amberlyst-15-promoted Knoevenagel reaction of β-ketosulfones and arylaldehydes in refluxing toluene; (ii) Grignard reagent (R'MgBr) or reducing reagent (NaBH4) promoted regio- and/or stereocontrolled 1,4-addition or 1,

Journal of Pharmaceutical Sciences, 1985
Aromatic hydroxylated derivatives of the spiro[indan-1,3'-pyrrolidine] and spiro[indan-2,2'-pyrrolidine] ring systems have been synthesized and evaluated for dopaminergic agonist and antagonist activities. None of these conformationally restricted catecholamines possessed any dopaminergic activity, but 5,6-dihydroxy spiro[indan-1,3'-pyrrolidine ...

HERBICIDAL PROPERTIES OF SUBSTITUTED INDANS
Canadian Journal of Plant Science, 1969The mixed isomers 1,1-dimethyl-4,6-diisopropyl-5-indanyl ethyl ketone and 1,1-dimethyl-4,6-diisopropyl-7-indanyl ethyl ketone (substituted indans) were assessed for their herbicidal properties under field, greenhouse, and growth chamber conditions.
