  and dicyclohexylcarbodiimide. The formed semi-stabilised ylides bear a metallated amide or amidine function. Their use in situ as Wittig reagents towards aldehydes and ketones is shown to be a new one-pot, E-stereoselective synthesis for αβ-unsaturated anilides and amidines. Moreover, the corresponding phosphonium salts were isolated.

  A series of anilide derivatives were synthesized and evaluated as inhibitors of recombinant human monoamine oxidase (MAO) A and B. The most potent inhibitors among the derivatives that were initially evaluated were (2E)-N-(3-chlorophenyl)-3-phenylprop-2-enamide (2c) and (2E)-N-(3-bromophenyl)-3-phenylprop-2-enamide (2d) with IC50 values of 0.53 mu M and 0.45 mu M, respectively. These derivatives exhibited reversible and selective inhibition of MAO-B with binding affinities 37 fold higher for MAO-B than for MAO-A. Analysis of the possible binding interactions of these inhibitors with active site models of human MAO-A and B led to the design of phenolic and benzonitrile derivatives of 2c and 2d. Among these were (2E)-N-(3-chlorophenyl)-3-(4-hydroxyphenyl)prop-2-enamide (7c) and (2E)-N-(3-bromophenyl)-3-(4-hydroxyphenyl)prop-2-enamide (7d) which inhibited MAO-B selectively and reversibly with IC50 values of 0.032 mu M and 0.026 mu M, respectively. These inhibitors were at least 14 fold more potent than 2c and 2d. This study concludes that N,3-diphenylprop-2-enamide is a suitable scaffold for the design of selective MAO-B inhibitors and structural modifications to enhance the binding affinities of the inhibitors for the MAO-B active site include substitution with halogens on the N-phenyl ring and substitution with hydroxyl and nitrile functional groups on the para and meta positions, respectively, of the C3 phenyl ring. Possible binding modes of these structures within the MAO-B active site are proposed with the emphasis on the interactions of the inhibitor halogens and the hydroxyl and nitrile functional groups with active site residues and water molecules.

• Synthesis of conjugated dienes <i>via</i> palladium-catalysed aerobic dehydrogenation of unsaturated acids and amides

  A Pd(II)-catalyzed direct aerobic dehydrogenation of γ,δ-olefinic acids and amides has been demonstrated. The present protocol dehydrogenates the least acidic amides and acids, thus replacing the traditional enolate strategy for dehydrogenation. A broad spectrum of conjugated dienamides and dienoic acids were produced in good to excellent yields. A possible reaction mechanism was proposed and supported
