Identify the reagents necessary to achieve the transformation below. You will need to use at least one reaction from this chapter and at least one reaction from the previous chapter. The essence of this problem is to choose reagents that will achieve the desired stereochemical outcome: OH - OH The transformation above can be performed with some reagent or combination of the reagents listed below. Give the necessary reagent(s) in the correct order, as a string of letters (without spaces or punctuation, such as "EBF"). If there is more than one correct solution, provide just one answer. B A RCO3H H2SO4, H20, HgSO4 cat. OsO4, NMO D E F H30 H2, Lindlar's cat. Na, NH3(0) Reagent(s)
