Vicinal dianions derived from diethyl a-aroylsuccinates were found to react with carbonyl compounds b-regioselectively to afford a-aroyl-g-butyrolactones, which were converted into a-arylidene-g-butyrolactones by reduction with H 2 /Pd-C followed by elimination employing methanesulfonyl chloride in

The photomediated generation of a-hydroxyalkyl radicals from simple acyclic and cyclic alcohols, and acyclic diols, and their subsequent carbon-carbon bond forming reaction with propiolate esters and acetylenedicarboxylates, gives a mixture of a b-(hydroxyalkyl)enoate, the result of a formal cis add
Allylic propiolates react with tributyl-or triphenylstannane to yield a-(stannyljmethylene-y-butyrolactones. a-Methylene-y-butyrolactones are easily prepared by destannylation.
