(a)
Interpretation: The type of sigmatropic rearrangement in the given equation is to be illustrated.
Concept introduction: Sigmatropic rearrangements are pericyclic reactions which involve the migration of sigma bonds. In these reactions, old sigma bonds are broken and new sigma bonds are formed.
Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the

- What is the major alkene formed when A is treated with POCl3 andpyridine? Explain why the major product is different in these reactions.arrow_forwardSuzuki coupling of aryl iodide A and vinylborane B affords compound C,which is converted to D in the presence of aqueous acid. Identifycompounds C and D and draw a stepwise mechanism for the conversionof C to D.arrow_forwardSulfur ylides, like the phosphorus ylides, are usefulintermediates in organic synthesis. Methyl trans-chrysanthemate, anintermediate in the synthesis of the insecticide pyrethrin I,can be prepared from diene A and a sulfur ylide. Draw a stepwisemechanism for this reaction.arrow_forward
- Draw a stepwise mechanism for the attached reaction, which involves two Friedel–Crafts reactions. B was an intermediate in the synthesis of the antidepressant sertralinearrow_forwardDraw the major organic product of the reaction. Ignore stereochemistryarrow_forwardDevise a stepwise synthesis of attached compound from dicyclopentadiene using a Diels–Alder reaction as one step. You may also use organic compounds having ≤ 4 C's, and any required organic or inorganicreagents.arrow_forward
- One step in the synthesis of the nonsteroidal anti-inflammatory drug rofecoxib (trade name Vioxx) involves Suzuki coupling of A and B. What product is formed in this reaction?arrow_forwardWhich heterocycles are more basic than pyrrole?arrow_forwardDraw a stepwise mechanism for the following Robinson annulation. This reaction was a key step in a synthesis of the steroid cortisone by R. B. Woodward and co-workers at Harvard University in 1951.arrow_forward
- Devise a synthesis of X from the given starting materials. You may useany organic or inorganic reagents. Account for the stereochemistryobserved in X.arrow_forward1. Draw the organic product (ignoring stereochemistry) 2. State whether the process is overall oxidation, overall reduction, or neither.arrow_forwardProvide the neccessary reagents next to the arrowsarrow_forward
