Question

Each of the following reactions has been reported in the chemical literature and proceeds in good yield. What are the principal organic products of each reaction? In some of the exercises more than one diastereomer may be possible, but one of them is either the major product or the only product. For those reactions in which one diastereomer is formed preferentially, indicate its expected stereochemistry.
