Sharpless epoxidation of allylic alcohol X forms compound Y. Treatment of Y with NaOH and C6H5SH in an alcohol–water mixture forms Z. Identify the structure of Y and draw a mechanism for the conversion of Y to Z. Account for the stereochemistry of the stereogenic centers in Z. Z has been used as an intermediate in the synthesis of chiral carbohydrates.
Draw the product and indicate the stereochemistry when the given alcohol is treated with each reagent: (a) HBr; (b) PBr3;
(c) HCI; (d) SOCI, and pyridine.
Compound W has molecular formula C₁4H18 and reacts with H₂ to form X. Oxidative cleavage of W with O3
followed by CH3 SCH3 affords Y. What is the structure of W?

- Compound A, C₁1 H160, was found to be an optically active alcohol. Despite its apparent unsaturation, no hydrogen was absorbed on catalytic reduction over a Pd/C catalyst. On treatment of A with dilute H₂SO4, dehydration occurred and an optically inactive alkene B, C₁₁H₁4 was produced as the major product. Alkene B, on ozonolysis, gave two products. Product C, C7H6O, was shown to be an aldehyde while product D, C4H8O, was shown to be a ketone.
