O-SILYLATED ENOLATE PHENYLTHIOALKYLATION: A NEW SYNTHESIS OF UNSATURATED 1,5-DICARBONYL COMPOUNDS.
Khan, Hassan A.,Paterson, Ian
, p. 2399 - 2402 (2007/10/02)
The O-silylated enolates of ketones and esters can be phenylthioalkylated by the chlorides (2) and (3) under ZnBr2-catalysis; ozonolysis and subsequent sulphoxide thermolysis then gives the corresponding unsaturated 1,5-dicarbonyl compounds.
