Part II. The following are steps from the total synthesis of the naturally occurring (5)-ladderane pentacycloanammoxic acid. Answer the questions about this synthesis. н ннн pentacycloanammoxic acid COH a) Propose a mechanism for this step. (Hint: have one of the alkenes react with Bry first to make the dibromide, then the remaining three alkenes will undergo a pericyclic reaction.] b) Propose a mechanism for the Diels-Alder reaction. The dienophile looks different than the ones we've seen, but the mechanism is...
