  日期：——

  A switchable synthesis of N-substituted indole derivatives from phenidones via rhodium-catalyzed redox-neutral C–H activation has been achieved. In this protocol, we firstly disclosed that the reactivity of Rh(III) catalysis could be enhanced through employing palladium acetate as an additive. Some representative features include external oxidant-free, applicable to terminal alkynes, short reaction

  A RhIII-catalysed ortho C–H amination of phenidones under mild conditions was developed using N-alkyl-O-benzoyl-hydroxylamines as aminating agents, and with a cyclic hydrazine moiety as a directing group, yields of up to 97 % and a high functional group tolerance were observed. This strategy offers an alternative route for the synthesis of amino analogues of the 5-lipoxygenase inhibitor phenidone, and

• 5-Lipoxygenase inhibitors: the synthesis and structure-activity relationships of a series of 1-phenyl-3-pyrazolidinones

  A series of analogues of the 5-lipoxygenase inhibitor 1-phenyl-3-pyrazolidinone (phenidone, 1a) has been prepared via two complementary new synthetic methods. The reaction of various electrophiles with the dianion of 1a or with an N-silylpyrazolidinone anion gave the desired 4-substituted pyrazolidinones (Scheme I and II). A new procedure was developed for the resolution of 4-substituted pyrazolidinones (Scheme V). A regression study on 21 compounds in this series showed a correlation of increased inhibitor potency (pIC50) with increased compound lipophilicity (log P) and with an N-phenyl electronic effect as measured by the C-13 NMR chemical shift parameter CNMR1' (R2 = 0.79). The most potent 5-lipoxygenase inhibitor in this series was 4-(ethylthio)-1-phenyl-3-pyrazolidinone (1n) with an IC50 of 60 nM. Another member of this series, 4-(2-methoxyethyl)-1-phenyl-3-pyrazolidinone (1f, IC50 = 0-48-mu-M), although less potent than 1n, was better tolerated in the whole animal relative to phenidone (1a) and also displayed good oral activity in two models of 5-lipoxygenase inhibition. On the basis of a structure-activity relationship study, a mechanism for the inhibition of 5-lipoxygenase by this class of inhibitors was proposed.
