# Solution: Consider the reaction given below. (a and b) Give the absolute configuration (R or S) for each of the indicated chiral centers. (c) Using arrows to show the flow of electrons, write a stepwise mechanism for this reaction. Be sure to show the stereochemistry that exists in each elementary step. Also be sure to show clearly how the chiral centers in the final product are formed.
