An access to highly enantioenrichedcis-3,5-disubstituted γ-lactones from α-bromoacetate and silyl enol ether

A novel synthetic strategy for highly enantioenrichedcis-3,5-disubstituted γ-lactones has been developed by the AgOTf-promoted nucleophilic substitution of α-bromoacetates with silyl enol ethers and subsequent reductive lactonization. The utility of this synthetic method was further demonstrated through the concise stereodivergent synthesis ofcis- andtrans-2,4-disubstituted tetrahydrofurans.

One-Pot Quinine-Catalyzed Synthesis of α-Chiral γ-Keto Esters: Enantioenriched Precursors of cis-α,γ-Substituted-γ-Butyrolactones

A highly enantioselective one-pot synthesis of important building blocks, α-chiral γ-keto esters, has been developed by combining a quinine-catalyzed Michael addition of malononitrile to trans-enones followed by magnesium monoperoxyphthalate (MMPP) oxidat

LACTONIZATION OF PHENYLCYCLOPROPANECARBOXYLIC ACIDS

The capacity of phenylcyclopropanecarboxylic acids for lactonization under the influence of mineral acids was studied.It was found that concentrated sulfuric acid at 20 deg C can give rise to lactonization only in the case where the intermediately formed carbocation is stabilized by a phenyl group.Preliminary isomerization to the corresponding unsaturated acid does not occur here.
