In presence of pyridine, benzenesulfphenyl chloride (1) adds on the methyl α- and β-methyl crotonates and methyl α- and β-methyl cinnamates (6-9) in regiospecific manner involving an onium intermediate such as (18).The product pattern is decided by the st

1,1-Dicarbonyl- (ester, ketone, lactone) substituted alkenes are prepared from the corresponding saturated 1-phenylsulfinyl derivatives.These are formed from precursor sulfides, which can be efficiently prepared either by oxidation of β-hydroxy-α-phenylsulfenylcarbonyl compounds or direct acylation of α-phenylsulfenyl enolate anions with acid chlorides.Some of the title compounds can be isolated and then reacted while others are generated and reacted in situ in a Diels-Alder fashion with cyclopentadiene.Endo-exo selectivities are discussed.
