A convenient method for lactonization of α-allyl esters using iodine in dimethylsulphoxide

A simple method for the synthesis of α-γ-disubstituted-γ-butyrolactones by cyclization of α-allyl esters using iodine in dimethylsulphoxide is reported. This method is efficient and operationally simple in comparison to methods using transition metal comp

Asymmetric olefin isomerization of butenolides via proton transfer catalysis by an organic molecule

An unprecedented enantioselective and general olefin isomerization was realized via biomimetic proton transfer catalysis with a new chiral organic catalyst. A broad range of mono- and disubstituted β,γ-unsaturated butenolides were transformed into the corresponding chiral α,β- unsaturated butenolides in high enantioselectivity and yield in the presence of as low as 0.5 mol % catalyst. Mechanistic studies have revealed the protonation as the rate-determining step.

A general synthetic approach to 5-alkyl-2(5H)furanones via 1,3-dipolar cycloaddition

[3+2] Cycloaddition methodology provides a general and efficient access to 5-alkyl substituted 2(5H)furanones. The synthetic approach has been exploited towards the synthesis of naturally occurring butenolides.
