Give the structure(s) of the product(s) the reaction below, and be sure to indicate any relative stereochemistry (you can assume that each of the Diels-Alder reactions will proceed with endo selectivity). Draw out relevant enantiomer(s) if they are expected to form. If no reaction is expected to occur under the indicated conditions, then write "no reaction" or NR, and explain why you would expect nothing to occur. If more than one product is formed, please indicate which one will be the major product or if they will be formed in equal amounts. In all cases, equimolar amounts of both components/reagents are present unless indicated otherwise I'm struggling to see how this reaction will go! I am wondering if it will cycle on itself but I'm not sure how I drew out a decagon but I'm a bit lost
