Question

Sulfur ylides, like the phosphorus ylides of Chapter 21, are useful intermediates in organic synthesis. Methyl trans-chrysanthemate, an intermediate in the synthesis of the insecticide pyrethrin I (Section 26.4), can be prepared from diene A and a sulfur ylide. Draw a stepwise mechanism for this reaction.
