A novel intermolecular synthesis of γ-lactones via visible-light photoredox catalysis

Direct γ-lactone formation via visible-light photoredox catalysis has been achieved efficiently including hydroxylalkylation of aromatic alkenes and transesterification. The present photocatalytic protocol has good regioselectivity and substrate compatibility, affording a novel way to intermolecular γ-lactone synthesis by the reaction of styrenes with α-bromo esters in the absence of any external oxidants.

Mn(III)-based reaction of alkenes with pyrrolidinedione derivatives. Formation of bicyclic peroxides and the related compounds

Alkenes (1) and 2,3-pyrrolidinediones (2) were treated with manganese(III) acetate in acetic acid at 23°C under a stream of dry air giving 1-hydroxy-8-aza-2,3-dioxabicyclo[4.3.0]nonan-9-ones (3) in good yields. The reaction at elevated temperature gave 4-ethenyl-2,3-pyrrolidinediones (6) and/or 4-alkyl-2,3-pyrrolidinediones (7) in good yields. A wide variety of 2,3-pyrrolidinediones having an alkoxycarbonyl, cyano, or acyl group at the 4-position were tested to delineate the scope and limitations of these reactions. The mechanisms for the formation of the products were also discussed.

Reaction of Olefins with Malonic Acid Derivatives in the Presence of Manganese(III) Acetate

The reaction of methylmalonic acid with mono- and disubstituted olefins in the presence of manganese(III) acetate yielded 2-carboxy-2-methyl-4-butanolides in moderate to good yields.The reactions of bromomalonic acid and chloromalonic acid with a variety

Epoxides : Part II - Synthesis of Butyrolactones

1,1-Diarylethylene oxides (Ia-c) react with diethyl malonate in the presence of sodium ethoxide to give γ,γ-diaryl-α-ethoxycarbonyl-γ-butyrolactones (IIa-c) which yield the carboxylactones (IIIa-c) upon alkaline hydrolysis.Decarboxylation of IIIa-c furnishes the corresponding γ,γ-diaryl-γ-butyrolactones (IVa-c).
