Deuterium (D, or 2H) is an isotope of hydrogen with atomic mass=2. Deuterium can be introduced into organic compounds by using reagents in which hydrogen has been replaced by deuterium. Outline preparation of the following compounds from the same alkene using appropriate deuterium-containing reagents. HO OH

a) Suggest a synthesis of the compound shown below. You are required to first do a retrosynthesis leading to commercially available starting material, and then the corresponding synthesis. In your synthesis, you may use any inorganic reagents you think I will assist in your synthesis, but can only use the following organic reagents; saturated hydrocarbon chain with 5 or less carbons and one functional group, unsaturated hydrocarbon chain with 5 or less carbons and one functional group in addition to the alkene or alkyne, saturated hydrocarbon ring with 6 or less carbons and one functional group, and unsaturated hydrocarbon ring with 6 or less carbons and one functional group. за

Spirocyclic compounds, such as compound 3, are made and used by insects for the purposes of communication. The first step of a synthesis of compound 3 involves treatment of (S)-1,2-epoxypropane (compound 1) with lithium acetylide, followed by acid workup, to give compound 2, as shown below (J. Org. Chem. 2005, 70, 3054-3065). Identify the structure of compound 2 and provide a mechanism for its formation. (Hint: The carbon-lithium bond reacts in a way that is similar to the carbon-magnesium bond of a Grignard reagent.) 1 13.17 a 1) Li—= 2) H₂O+ нас!!!!!!
