The selective syntheses of 1- and 2-indan-one compounds from 2-ethynylbenzyl ethers have been achieved with suitable catalysts and solvents. The highly acidic [tris(pentafluorophenyl)phos-phine]gold hexafluoroantimonate [(C6F5)3AuSbF6] in nitromethane (MeNO2) preferably gives 1-indan-ones whereas [(ortho-biphenyl) di(tert-butyl)phosphine] gold triflimide [(tBu)2(o-biphenyl) AuNTf2] in dichloroethane tends to form 2-indanone derivatives. For 2-indanone products, we isolated two indenyl methyl ethers for deuterium labeling analyses, providing evidence for p-alkyne activation.

A study of the effect of aromatic substitution on D1 and D2 affinity in a series of previously reported trans-1-piperazino-3-phenylindans shows similar structure-activity relationships for the two receptor sites. 6-Substituted derivatives have affinity for both receptors, and 6-chloro-or 6-fluoro-substituted derivatives show preference for D1 receptors.D1 affinity and selectivity are significantly increased in a series of new piperazine ring substituted derivatives.Potent D1 and D2 antagonism in vivo are confined to derivatives with relatively small substituents in the 2-position of the piperazine ring (e.g. 2-methyl, 2,2-dimethyl, 2-spirocyclobutyl or 2-spiro-cyclopentyl).Consequently, the effect of aromatic substitution is examined in a series of 1-(2,2-dimethylpiperazino)-3-arylindans.All these compounds except the 4-, 5-, 7- and 4'-chloro-substituted derivatives have potent D1 affinity (IC50's below 10 nM) and the majority of the compounds antagonize SKF 38393-induced circling in 6-OHDA-lesioned rats with ED50 values about 1μmol/kg.In vitro all compounds show preference for D1 receptors, but in vivo they are equally effective as D1 and D2 antagonists.The compounds have high affinity for 5-HT2 receptors and selected compounds show high affinity for α1 adrenoceptors.Furthermore, a subgroup consisting of (-)-38, (-)-39, (-)-41, and (-)-54 does not induce catalepsy in rats.These compounds have the potential of being "atypical" antipsychotics and have consequently been selected for further studies.The non-receptor-blocking enantiomers are shown to be inhibitors of DA and NE uptake in accordance with previous observations in compounds unsubstituted in the piperazinering.Two compounds, (+)-38 and (+)-40, block DA uptake with IC50 values below 10nM.Finally, the observed structure-activity relationships are discussed in relation to previously published pharmacophore models for D2 and 5-HT2 receptors.It is concluded that the piperazine substituents might induce a different binding mode at the dopamine receptor sites, perhaps only at the D1 receptor site.
Application of (2-Cyanoaryl)arylacetonitriles in Cyclization and Annulation Reactions. Preparation of 3-Arylindans, 4-Aryl-3,4-dihydronaphthalenes, 4-Arylisoquinolines, 1-Aminonaphthalenes, and Heterocyclic Analogues

(2-Cyanoaryl)arylacetonitriles, obtained from o-halogen-substituted cyanoaromatics and arylacetonitriles may be alkylated with methyl chloroacetate.Subsequent abstraction of the proton adjacent to the ester group followed by attack of the anion at the aromatic cyano group gives rise to annulated 1-aminocyclopentenes by a Dieckmann-type reaction.The homologous esters similarly produce annulated 1-aminocyclohexenes.The generality of this annulation method is demonstrated by preparation of derivatives of 1-amino-1H-indene, 4-amino-6H-cyclopentathiophene, 5-amino-7H-pyrindine, 1-amino-3,4-dihydronaphthalene, and 5-amino-2,9-dihydro-1H-cyclopentisoquinoline.Hydrolysis and decarboxylation of these compounds leads to ketones as exemplified by synthesis of 3-arylindan-1-ones and 4-aryl-3,4-dihydro-1(2H)-naphthalen-1-ones.When treated with hydrogen bromide, the (2-cyanophenyl)phenylacetonitriles cyclize to -condensed 3-bromo-5-aryl-6-aminopyridines.Thus, derivatives of isoquinoline, thienopyridine, and 1,6-naphthyridine were prepared.
