observed for certain 3,5-diacyl-2,4-dialkyl-6-phenylpyridine derivatives in displacement of [125I]AB-MECA (N6-(4-amino-3-iodobenzyl)-5'-N-methylcarbamoyladenosine) at recombinant human A3adenosinereceptors. Selectivity for A3adenosinereceptors was determined vs radioligand binding at rat brain A1 and A2A receptors. Structure-activityrelationships at various positions of the pyridine ring (the 3- and

The selectivity of sulfonylation of β‐keto esters with sodium sulfinates under the action of iron(III) can be regulated by the solvent nature and reaction temperature. As a result, α‐sulfonyl β‐keto esters or α‐sulfonyl esters can be selectively obtained. Application of β‐diketones as starting materials gives only α‐sulfonyl ketones.
The invention relates to specific ketones of formula (I) which act as photolabile pro-fragrances. The invention further relates to detergents or cleaning agents, cosmetic agents and air freshening products including ketones of said type. The invention also relates to a method for lastingly scenting surfaces and a method for lastingly fragrancing rooms using said ketones.
