Hydroboration
46PRACTICE PROBLEM
Using 1-methylcyclohex-1-ene, an achiral reagent, as the starting material in a hydroboration reaction, the products are chiral, a racemic mixture of trans-2,4-dimethylcyclopentan-1-ol. The formation of one of the enantiomers is given below. Propose a synthesis that shows how the other enantiomer was formed.
