The following two-step synthesis gave compound F as the major product. 1.1, THE 2. NaN,, acetone HO (0) Assign the configuration of the two chirality centres generated in the synthesis, using the CIP rules, (8) () Explain with the aid of a reaction mechanism why F was the major stereoisomer formed, and draw the structure of a stereoisomer that might be formed as a minor product. (15) (I) Draw the structures of the enantiomer, and one epimer, of F, and give definitions of these terms. (12)
