2. There are two types of mechanisms for epoxide openings. Use the examples below to: Describe the two pathways for epoxide opening (when do they usually occur? What should you look for? Etc.) a. Explain why two different products are formed in these two examples. Include mechanisms for both reactions. b. Pathway 1: Pathway 2: HCI OCH3 NaOCH3 OH HO H3CO CH3OH CH3OH
Can you help me understand the two pathways for
Given: Reactions
To find: The mechanism of the above reactions and give out a reason why the products formed are different.
Solution: Epoxide is a cyclic ether. In both the Reactions opening of epoxide ring takes place .
In the above reaction if the Epoxide ring opening takes place in presence of strong acid then the attack takes place from backward side and the group which is on dash will go on wedge.
But if the Epoxide ring opening takes place in presence of base than the attack takes place from same side and the group which is on dash will remain on dash or which remain on wedge will remain on wedge only.
