Abstract
A regioselective [3+2] cyclisation reaction between 2-arylidene-1,3-indanedione and ethyl 2,3-butadienoate catalysed by triphenylphosphine has been demonstrated to synthesize functionalised spirocyclic cyclopentenes. The reaction tolerated various electron-rich and electron-deficient aryl substituted 2-arylidene-1,3-indanediones with high to excellent chemical yields (up to 99%) and moderate to good regioselectivity (up to 5 : 1). DFT studies have also been carried out to understand the regioselective nature of this reaction. The results of Frontier molecular orbital calculations and the activation energy (Ea) favour the formation of compound 3avia γ-attack compared to that of 4avia α-attack. A [3+2] annulation protocol for the construction of functionalized spirocyclopentenes utilizing 1,3-indanedione derived benzylidene-1,3-indanedione and ethyl-2,3-butadienoate at room temperature was developed.![]()

Abstract
A selected set of new N1-(indan-5-yl)amidrazones 4a-p, encompassing piperazines or
related amines, has been prepared via interaction of the hydrazonoyl chloride 3 (derived from
5-aminoindane) with the appropriate sec-cyclic amine in the presence of triethylamine. Their suggested
structures are supported by IR, <sup>1</sup>H NMR, <sup>13</sup>C NMR, high-resolution MS (ESI) spectral data, and further
confirmed by single-crystal X-ray crystallography for 4k. These novel compounds were screened for
their antitumor activity against breast cancer cells (MCF7 and T47D); amongst all of them, only compound
4o, incorporating N-(pyrimidin-2-yl)piperazine, was fairly active with IC<sub>50</sub> values of 69 μM and
61 μM, respectively.

Abstract
We report a facile and highly efficient method that copper-catalyzed intramolecular annulation to synthesize 3-hydroxy-1-indanones employing simple 2-ethynylbenzaldehyde as starting materials was achieved successfully. This protocol provided a simple synthetic approach to afford 3-hydroxy-1-indanones under mild conditions in good to excellent yields.

Abstract
The indane (2,3-dihydro-1H-indene) ring system is an attractive scaffold for biologically active compounds due to the combination of aromatic and aliphatic properties fused together in one rigid system. This bicyclic structure provides a wide range of possibilities to incorporate specific substituents in different directionalities, thus being an attractive scaffold for medicinal chemists. Notably, many indane-based compounds are being used in the clinic to treat various diseases, such as indinavir, an HIV-1 protease inhibitor; indantadol, a potent Monoamine Oxidase (MAO)-inhibitor; the amine uptake inhibitor indatraline; and the ultra-long-acting β-adrenoceptor agonist indacaterol. Given the diversity of targets these drugs act on, one could argue that the indane ring system is a privileged substructure. In the present review, the synthetic and medicinal chemistry of the indane ring system is described. In more detail, it contains a comprehensive overview of compounds bearing the indane substructure with G protein coupled receptor (GPCR) activity, with particular emphasis on their structure-activity relationships (SAR).
