During many organic syntheses it is a common practice to introduce a sily other protecting group to ask the activity of an OH group. In this example, the silyl group chosen is the triisopropylsity group, Draw the product of the following transformation, assuming that the trisopropylsily C reagent reacts only once with the starting material Me Me Pr OH iPSi Pr HO ci Me DMAP (base) EIN NH Use the wedge/lash bond tools to indicate stereochemistry where it is For your convenience, the starting material has been drawn for you in the sketchpad CP 0 D
