) The reduction of a cyclohexanone 7 to the corresponding cyclohexanol 8 is shown below. Choose a suitable hydride reducing agent for this reaction and then suggest appropriate alkyl substituents for the ' R ' and ' R ' groups that will lead to the observed stereochemistry of cyclohexanol 8. Your answer should also include appropriate 3-D diagrams to explain the origins of the stereoselectivity and explain your choice of reducing agent. [8 marks]
