General description

Phenyl vinyl sulfoxide reacts with lithium enolates of ketones at -78°C in THF to yield bicyclo[n.2.0]alkan-1-ols. It also reacts with in situ generated (dialkylamino)magnesium reagent to yield symmetrical β-(dialkylamino)dithioacetals. It participates as an acetylene equivalent in Diels-Alder reactions.

Diels–Alder Reaction

The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. Since the reaction involves the formation of a cyclic product via a cyclic transition state, it is also referred to as a "cycloaddition".
