Thioreductones and Derivatives (G)

Abstract: Thioreductones and DerivativesReplacement of one or two (principally also three) O-atoms in aci-reductones by sulfur leads to the corresponding thioreductones. In the present paper, different methods of their synthesis are discussed. Substitution of the bromo nucleofug in the 2-position of 1,3-dicarbonyl compounds as well as of a 3oxosulfone by selected sulfur nucleophiles is assumed to follow an S RN 1 pathway. Characteristic properties, some typical reactions, and selected derivatives were studied. S-Alkyl-a… Show more

“…Since the selectivity of dimedone for protein sulfenic acids is well established, our initial goal was to transform this cyclic 1,3-diketone into a thiolreactive probe. From literature examples of thiourea Salkyation by 1,3-dicarbonyl halides, [13] we reasoned that installation of iodine at the 2-position of the dimedone scaffold would furnish the requisite trapping reagent (Scheme 2 b; see also Figure S1 in the Supporting Information).…”
