1. Give the structure(s) of the product(s) for each of the reactions below, and be sure to indicate any relative stereochemistry (you can assume that each of the Diels-Alder reactions will proceed with endo selectivity). 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. ttBuOK 1) KMnO4,NaOH 2) HNO3,H2SO4
