Question

Please answer the following question correctly and completely. (Please write neatly)

1. Take a look at this figure and do the followng:

A. Write the appropriate reaction conditions/reagents listed over each arrow (Circled in red).

B. There are four stereoisomers shown for intermediate "4" but only one for "5". The word "resolved" is written over the arrow between them. What does resolved mean? How might we be converting a mixture of four structures into only one structure?

C. Write step-by-step mechanisms (with appropriate curved arrows, formal charges, mechanism intermediates, lone pairs as needed) for All three steps: 1->2 and 2->3 and 6->7 (shown in the green arrows).
