  A novel series of rigidized indolyl pyrrolidine derivatives have been designed by constraining the tryptamine nitrogen through a and b carbons. All the synthesized derivatives have shown moderate affinities at 5-HT6R when tested in in vitro binding assay.

  A series of indole and 5-methoxyindole derivatives, substituted at C3 with n-propyl or 4-methylcyclohexyl scaffolds bearing varying degrees of fluorination of the terminal methyl group, have been prepared and studied. These compounds exhibit characteristic polarity patterns, measured either by log P or chromatographic capacity factors, which are consistent with the partially known lipophilicity pattern

  日期：2009.3.19

  Unsymmetrical 3,4-disubstituted maleimides have been synthesized by palladium-catalyzed cross-coupling reactions of indium organometallics with 3,4-dihalomaleimides. The synthesis was performed by stepwise or sequential one-pot palladium-catalyzed cross-coupling reactions with various triorganoindium reagents. This method was used to prepare a wide variety of alkyl, aryl, heteroaryl, and alkynyl 3

• Further Studies on Oxygenated Tryptamines with LSD-like Activity Incorporating a Chiral Pyrrolidine Moiety into the Side Chain

  The enantiomers of 3-(N-methylpyrrolidin-2-ylmethyl)-5-methoxyindole, 1, and 3-(N-methylpyrrolidin-2-ylmethyl)-4-hydoxyindole, 3, were prepared using an asymmetric synthesis that employed (+)- or (-)-proline. A new approach was developed that had certain advantages over the synthesis originally reported for the isomers of 1. (+)-3-(N-Methylpyrrolidin-3-yl)-4-hydroxyindole, 5, was also prepared as a rigid analogue of psilocin and compared with its 5-methoxy counterpart 4. Radioligand competition assays were used to assess the affinity of compounds for the 5-HT2A receptor labeled with the agonist ligand [I-125]DOI and the antagonist ligand [H-3]MDL100907. Two-lever drug discrimination assays in rats trained to discriminate either LSD or DOI from saline were employed to assess the hallucinogen-like behavioral properties of these rigid tryptamine analogues. The receptor binding assay results clearly demonstrated a stereochemical preference for the R enantiomers that did not discriminate the position of the oxygen function. The receptor is 10-20-fold more selective for the R isomers. The affinities of the R enantiomers were virtually identical for both 1 and 3 at the agonist-labeled receptor, while racemic 4 and 5 had about one-tenth the affinity. The drug discrimination data in both LSD- and DOI-trained rats paralleled the binding data using [I-125]DOI displacement. Both (R)-1 and (R)-3 are about equipotent, comparable to DOI in activity but about 10-fold less potent than LSD. Compound 4 produced only partial substitution, even at a dose nearly 5-fold higher than for (R)-1. Based on conformational energies, it seems doubtful that these compounds bind to the 5-HT2A receptor in an ergoline-like conformation. The results also suggest that both 1 and 3 would possess LSD-like psychopharmacology in humans.

  The preparation of 4-, 5-, and 6-methoxy substituted 3-lithio-1-(trialkylsilyl)indoles 4b-d by metalation of the corresponding 3-bromoindoles, and their reactions with iodomethane, DMF, ethylene oxide and aziridines are reported. Transmetalation of 3-lithioindoles 4b-d with ZnCl2 afforded 3-indolylzinc chlorides 11b-d, which underwent Pd(0)-catalyzed cross-coupling reactions with 2-halopyridines to give 4-, 5-, and 6-methoxy substituted 3-(2-pyridyl)indoles.
