Map at assify these structures as hemiacetal, hemiketal, acetal, ketal, or other. Each structure needs to go int a box, and they will shrink to fit as needed when you put more than one in a box. Jasperse: Read the hint before you start, because I didn't emphasize the distinction between hemiacetals and hemiketals, or between acetals and ketals.

Challenge Problem 18.38 The following is an example of a reaction sequence developed by Derin C. D'Amico and Michael E. Jung (UCLA) that results in enantiospecific formation of two new chirality centers and a carbon-carbon bond. The sequence includes a Horner-Wadsworth-Emmons reaction, a Sharpless asymmetric epoxidation, and a novel rearrangement that ultimately leads to the product. Propose a mechanism for rearrangement of the epoxy alcohol under the conditions shown to form the aldol product. (Hint: The rearrangement can also be...
