- Provide the suitable reagents to effect the following transformations. I specifically need help on sub-parts d, e, f, g, h, and i.Draw the product Y of the following reaction sequence. Y was anintermediate in the remarkable synthesis of cyclooctatetraene by RichardWillstatter in 1911.Answer the following question about curcumin, a yellow pigmentisolated from turmeric, a tropical perennial in the ginger family and aprincipal ingredient in curry powder. Most enols, compounds that contain a hydroxy group bonded to a C=C, are unstable and tautomerize to carbonyl groups. Draw the keto form of the enol of curcumin, and explain why the enol is more stable than many other enols.
