Devise the most efficient synthesis for the carboxylic acid
below using a starting material and reagents from the tables. Give
your route by specifying the number of the starting material
followed by the letters of the reagents you would use beginning
with the first step.
The answer 4fh means treat t-butanol(4)
with conc. HCl(f) then treat the product with KOH in
alcohol(h).

Provide a sequence of reaction to convert the starting material
to the product. Show all reagents and synthetic intermediates. You
can use any addition carbon sources if needed but you must use the
starting material given. The mechanisms do not have to be
shown.
Synthesis 1. The following transformations cannot be perfor Uwing transformations cannot be performed in one step. Provide a sequence of reactions 10 convert the "starting material" to the "product." Show all the reagents and synthetic intermediates....
5) Devise a synthesis (series of reactions) to transform each starting material into the desired given product using the starting aromatic source and any reagents necessary. Show all reaction steps and their resulting intermediate products. он
5. Devise a multi-step synthesis that will provide the product shown from the given starting material. (Challenging!) 6 Multiple Steps 3. When diastereomers I and I undergo an E2 elimination on treatment with sodium ethoxide in ethanol, one of the isomers react 500 times faster than the other one. Also, one isomer gives only A as a product and the other isomer gives a mixture of A and B as products. Determine the products of each isomer and explain your...
