    3-(4-Fluoropiperidin-3-yl)-2-phenylindoles as High Affinity, Selective, and Orally Bioavailable h5-HT2A Receptor Antagonists
    摘要:
    The development of very high affinity, selective, and bioavailable h5-HT2A receptor antagonists is described. By investigation of the optimal position for the basic nitrogen in a series of 2-phenyl-3-piperidylindoles, it was found that with the basic nitrogen at the S-position of the piperidine it was not necessary to further substitute the piperidine in order to obtain good binding at h5-HT2A receptors. This meant the compounds no longer had high affinity at the IKr potassium channel, an issue with previous series of 2-aryl-3-(4-piperidyl)indoles. Improvements could be made to oral bioavailability in this series by reduction of the pK(a) of the basic nitrogen, by adding a fluorine atom to the piperidine ring, leading to 3-(4-fluoropiperidin-3-yl)-2-phenyl-1H-indole (17). Metabolic studies with this compound identified oxidation at the B-position of the indole as a major route in vitro and in vivo in rats. Blocking this position with a fluorine atom led to 6-fluoro-3-(4-fluoropiperidin-3-yl)-2-phenyl-1H-indole (22), an antagonist with 0.06 nM affinity for h5-HT2A receptors, with bioavailability of 80% and half-life of 12 h in rats.

    A de novo synthesis of novel polyhydroxylated N-alkoxypiperidines based on the ring-closing double reductive amination of 1,5-dialdehydes, obtained by oxidative cleavage of cyclopentene derivatives, with O-substituted hydroxylamines is reported. Isofagomine was accessed by cleavage of the N–O bond of an N-alkoxypiperidine.

    lic acid (1) was synthesized for potential use in boron neutron capture therapy. Starting from the readily available 3-(bromomethyl)cyclobutanone ketal (4), several synthetic routes to 1 were evaluated. After several unsuccessful attempts with traditional synthetic methods, a novel synthetic strategy to generate the new boronated cyclic amino acid was developed. The tolerance of the hydantoin group

    Herein, we describe the total synthesis of janadolide, along with eight simplified analogues, via an efficient solid-phase strategy. Crucial to the synthesis of the natural product was the construction of a key polyketide fragment via an enantioselective (−)-B-chlorodiisopinocampheylborane-mediated reduction and a B-alkyl Suzuki reaction. Janadolide and the simplified analogues exhibited antitrypanosomal

    [reaction: see text] 2-Vinyloxiranes have been found to be excellent surrogates to beta,gamma-unsaturated aldehydes. These valuable electrophiles, generated in situ by treatment of a 2-vinyloxirane with a catalytic amount of Sc(OTf)(3), are effectively trapped by the chiral allylating agents based on alpha-pinene, affording bishomoallylic alcohols in high yield and excellent selectivity.
