Searching for novel antiobesity agents, a series of cannabinoid LH21 and of Rimonabant-fatty acid amide analogues have been prepared. Synthesis of pyrazoles 2a-2c was achieved by a two steps simple methodology via α,β-unsaturated ketones. Carboxamides 8a-8h were obtained in good yields from esters 7a-7c by a one-pot procedure which takes place under mild conditions. New compounds have been evaluated in vivo as anorectic agents. Some of them showed interesting properties reducing food intake in rats by a mechanism which does not involve the endocannabinoid system.

An EZ switch: The cationic species of the heteropoly compounds has a critical impact on the Z/E selectivity of the Meyer-Schuster rearrangement of propargyl alcohols (see scheme). The isolation of the thermodynamically unfavorable Z-α,β-unsaturated carbonyl compounds is notable. The high Z selectivities were obtained at a reaction temperature as high as 50°C.
