Abstract
Anxioselective agents may be identified among compounds binding selectively to the alpha(2)beta(x)gamma(2) subtype of the gamma-aminobutyric acid-A (GABA(A))/central benzodiazepine receptor (BzR) complex and behaving as agonists or among compounds binding with comparable potency to various BzR subtypes but eliciting agonism only at the alpha(2)beta(x)gamma(2) receptor. Because of subtle steric differences among BzR subtypes, the latter approach has proved much more successful. A biological screening within the class of indol-3-ylglyoxylamides 1-3 allowed us to identify compounds 1c and 2b as potential anxiolytic/nonsedative agents showing alpha(2) selective efficacy in vitro and anxioselective effects in vivo. According to molecular modeling studies, and consistently with SARs accumulated in the past decade, 5-NO(2)- and 5-H-indole derivatives would preferentially bind to BzR by placing the indole ring in the L(Di) and the L(2) receptor binding sites, respectively.

Abstract
The chemical stability and reactivity of hydroxy-1-aminoindans and their N-propargyl derivatives are strongly affected by the position of the OH group and its orientation relative to that of the amino moiety. Thus, the 4- and 6-OH regioisomers were found to be stable, while the 5-OH analogues were found to be inherently unstable as the free bases. The latter, having a para orientation between the OH and the amino moieties, could be isolated only as their hydrochloride salts. 7-Hydroxy-1-aminoindans and 7-hydroxy-1-propargylaminoindans represent an intermediate case; while sufficiently stable even as free bases, they exhibit, under certain experimental conditions, unexpected reactivity. The instability of the 5- and 7-hydroxy-aminoindans is attributed to their facile conversion to the corresponding, reactive quinone methide (QM) intermediates. The o-QM obtained from 7-hydroxy-aminoindans was successfully trapped with ethyl vinyl ether via a Diels-Alder reaction to give tricyclic acetals 32a,b.

Abstract
A new planar-chiral bidentate phosphaferrocene ligand (2) has been synthesized and structurally characterized. The derived rhodium complex, [Rh(cod)(2)]BF(4), serves as an effective catalyst for asymmetric isomerizations of allylic alcohols to aldehydes, furnishing improved yields, scope, and enantioselectivities relative to previously reported methods. The catalyst is air-stable and can be recovered at the end of the reaction. Mechanistic studies establish that the isomerization proceeds via an intramolecular 1,3-hydrogen migration and that the catalyst differentiates between the enantiotopic C1 hydrogens.

Abstract
A series of four racemic ring-substituted trans-2-(indol-3-yl)cyclopropylamine derivatives was synthesized and tested for affinity at the 5-HT1A receptor, by competition with [3H]-8-OH-DPAT in rat hippocampal homogenates, and for affinity at the agonist-labeled cloned human 5-HT2A, 5-HT2B, and 5-HT2C receptor subtypes. None of the compounds had high affinity for the 5-HT1A receptor, with the 5-methoxy substitution being most potent (40 nM). At the 5-HT2A and 5-HT2B receptor isoforms, most of the compounds lacked high affinity. At the 5-HT2C receptor, however, affinities were considerably higher. The 5-fluoro-substituted compound was most potent, with a Ki at the 5-HT2C receptor of 1.9 nM. In addition, the 1R,2S-(-) and 1S,2R-(+) enantiomers of the unsubstituted compound were also evaluated at the 5-HT2 isoforms. While the 1R,2S enantiomer had higher affinity at the 5-HT2A and 5-HT2B sites, the 1S,2R isomer had highest affinity at the 5-HT2C receptor. This reversal of stereoselectivity may offer leads to the development of a selective 5-HT2C receptor agonist. The cyclopropylamine moiety therefore appears to be a good strategy for rigidification of the ethylamine side chain only for tryptamines that bind to the 5-HT2C receptor isoform.
