Provide reagents for the first transformation

1) Make sure to show all intermediates and reagents for the transformation shown below. OH

Draw the major product of this SN1 reaction. Ignore any inorganic byproducts.

Name/label the functional group in the starting material below. Next, predict the major product of the reaction. Finally, draw a complete curved arrow mechanism that accounts for the product. Remember to show all proton transfers! OCH3 H3O+

Draw this compound in a chair form so that an E2 reaction is possible. Then, draw the mechanism and the major product. Your solution and structures must clearly show the 3D nature of the E2 mechanism.

Draw the structure of each of the organic precursors in the following two-step synthesis.

Show the product of each synthetic step. Draw mechanisms. Ph OH 1) NaH, then coa Br 2) DIBAH, then aq. workup 3) Ph₂P=CH₂ Ph 2 Grubbs catalyst Ph 3
