Question: Draw the product of each asymmetric epoxidation reaction.

Short Answer

Expert verified

Answer

Step by step solution

01

Asymmetric epoxidation

  • Asymmetric epoxidation is also known as Sharpless epoxidation.
  • Allyl alcohols participate in this reaction.
  • DET affects the stereochemistry of the product.If it is of (+)-DET, then the epoxide is formed below the plane, and if it is (-)-DET, then the epoxide is formed above the plane.
02

Products of the given reaction

The double bond of the alkene reacts with the sharpless reagent and forms the epoxide.

The specialty of the reaction is that it forms one of the stereoisomers in excess. Hence, the selective product can be obtained by using a suitable reagent.

The formation of products for the given reactions is shown below.
